2a) mesh network function
As specified, balloon 102A to 102F can collectively act as mesh network.More specifically, because balloon 102A extremely
102F can utilize free space optical link with communicating with one another, so these balloons can collectively act as Free Space Optics mesh network
Network.
In mesh network configuration, each balloon 102A to 102F may act as the node of mesh network, and the node is operable
It is sent to its data to receive and routes data to other balloons.In this way, by determining between source gas ball and destination balloon
Optical link appropriate sequence, data can be routed to destination balloon from source gas ball.These optical links are for source gas ball and mesh
Ground balloon between connection may be collectively referred to herein as " light path (lightpath) ".In addition, each optical link is referred to alternatively as in light path
" jumping (hop) ".
In order to which as mesh network operation, various route technologies and self-regeneration algorithm can be used in balloon 102A to 102F.
In some embodiments, adaptive or dynamic routing can be used in balloon network 100, wherein between source gas ball and destination balloon
Light path is determined and establishes, and some time is released from afterwards when needing connection.In addition, when using adaptive routing, it can
Light path is dynamically determined according to current state, past state and/or the predicted state of balloon network.
In addition, as balloon 102A to 102F is relative to each other and/or relative to ground moving, network topology can change.
Therefore, example balloon network 100 can update the state of network using MESH protocol come the change in topology with network.For example,
In order to solve the mobility of balloon 102A to 102F, balloon network 100 can be used and/or adaptively change mobile self-grouping network
The various technologies used in (mobile ad hoc network, MANET).Other examples are also possible.
In some implementations, balloon network 100 can be configured as transparent mesh network.More specifically, transparent
In balloon network, balloon may include the component of the physical exchange for complete optics, wherein in the physics routing of optical signal
It is not related to any electric component.So as to which in the transparent configuration exchanged with optics, signal is passed through the multi-hop light of complete optics
Road.
In other realization methods, balloon network 100 can realize opaque Free Space Optics mesh network.Impermeable
In bright configuration, some or all balloons 102A to 102F can realize optical-electrical-optical (optical-electrical-optical,
OEO it) exchanges.For example, some or all balloons may include that the optical crossover of the OEO conversions for optical signal connects (optical
Cross-connect, OXC).Other opaque configurations are also possible.Extraly, including both with transparent segment or with not
The network configuration of the routed path of transparent segment is possible.
In another aspect, the balloon in example balloon network 100 can realize wavelength-division multiplex (wavelength
Division multiplexing, WDM), this can help to increase link capacity.When realizing WDM with transparent exchange, across gas
The physics light path of net network can be by " wavelength continuity constraint ".More specifically, because the exchange in transparent network is complete
Optics, it is possible that assigning identical wavelength it is necessary to all optical links in given light path.
On the other hand, opaque configuration can avoid wavelength continuity from constraining.Specifically, the balloon in opaque balloon network
It may include can be used to the OEO exchange systems of wavelength convert.As a result, balloon conversion light can be believed at each jump along light path
Number wavelength.Alternatively, optical wavelength conversion can occur only at the selected jump along light path.
In addition, various routing algorithms can be used in opaque configuration.For example, in order to determine main optical path for given connection
And/or Shortest path routing technology can be applied or be considered to one or more different spare light paths, example balloon, such as
The algorithm and k shortest paths and/or edge and node diverse or disjoint path of Dijkstra is by the algorithm of such as Suurballe
Etc..Additionally or alternatively, it can be used to maintain certain quality of service (quality of when determining light path
Service, QoS) technology.Other technologies are also possible.
2b) station keeps function
In the exemplary embodiment, balloon network 100 can realize that the station keeps function to help to provide desired network topology.
It maintains and/or is moved to relative to one or more of network for example, station holding can relate to each balloon 102A to 102F
The specific position (and may be in specific position relative to ground) of other balloons.As a part of this process, Mei Geqi
Ball 102A to 102F can realize that the station keeps function to determine that it is expected the expected location in topology, and if necessary, then
It determines how and is moved to desired locations.
It is expected that topology can be different according to specific realization method.In some cases, balloon can realize that the station is protected
It holds to provide substantially uniform topology.In this case, given balloon 102A to 102F can realize that the station keeps work(
Its own can be located in the neighbouring balloon in balloon network 100 at a distance of substantially same distance (or in a spacing
From in the range of).
In other cases, balloon network 100 can have non-uniform topology.For example, example embodiment can relate to it is following
Topology:In these topologys, due to various reasons, balloon is distributed more dense or less dense in some regions.As showing
Example, in order to help to meet typical more high bandwidth requirements in urban area, balloon can more densely packed cluster on urban area.
Due to similar, the land side that is distributed in of balloon can be more more dense than above big water body.The many of non-uniform topology
Other examples are possible.
In another aspect, the topology of example balloon network can be that adaptability is changed.Specifically, example balloon
The station keeps function to allow balloon according to the variation of the expectation topology of network to adjust its respective positioning.For example, one or
Multiple balloons can be moved into new position to increase or reduce the density of balloon in given area.Other examples are possible.
In some embodiments, energy function can be used to determine whether balloon should move and/or answer in balloon network 100
Desired topology is provided when how to move.Specifically, the state of given balloon and the state of some or all neighbouring balloons can
To be the input of energy function.The current state of given balloon and neighbouring balloon can be applied to desired network-like by energy function
State (for example, with it is expected the corresponding state of topology).Then it can determine the given gas of instruction by determining the gradient of energy function
The vector of the expectation movement of ball.Given balloon then can determine in order to realize desired movement and the appropriate action to be taken.Example
Such as, balloon can determine that one or more height are adjusted so that wind will move balloon in the desired manner.

To determine present topology.Topology can provide available current optical link in balloon network and/or the wavelength availability of chain road
View.This topology then may be sent to that some or all of balloon, so that using route technology come to pass through
The communication of balloon network 204 selects appropriate light path (and may select spare light path).
In another aspect, central control system 200 (and area control system 202A to 202C may also) can also be
Balloon network 204 coordinates certain stations and keeps function.For example, central control system 200 can be connecing from balloon 206A to 206I
The status information of receipts is input to energy function, which can effectively carry out the present topology of network and desired topology

Divide coherent condition information.These balloons then coordinated with each other can determine the integrality of network.
In addition, in certain aspects, can partially or completely localize to balloon network-based control, so that its
Integrality independent of network.For example, individual balloon can realize that the station for only considering balloon nearby keeps function.Specifically
Ground, each balloon can realize the energy function that the state by its own state and neighbouring balloon is taken into account.The energy function can
For maintaining and/or being moved to the desired locations relative to neighbouring balloon, without considering the expectation topology of network on the whole.So
And when each balloon in order to the station keep realize this energy function when, balloon network can maintain on the whole it is desired topology and/
It is or mobile towards desired topology.
As an example, each balloon A can be received relative to the range information d of each in its k nearest-neighbors1To dk。
Each balloon A can be virtual spring be considered as, wherein vector is represented from the first arest neighbors to the distance of each in k balloon
Balloon i is occupied towards the force direction of balloon A, and the amplitude and d of poweriIt is proportional.Balloon A can seek each in k vector
With, and summation vector is the vector of the expectation movement of balloon A.Balloon A can attempt to realize desired by controlling its height
It is mobile.
Alternatively, this process can for example assign the power amplitude of each in these fictitious forces to be equal to di×di.For net
It is possible that each balloon in shape network, which assigns other algorithms of power amplitude,.
In another embodiment, similar process can be performed for each in k balloon, and each balloon can incite somebody to action
Its motion-vector planned is sent to its local neighbour.The more wheels of the plan motion-vector of each balloon are become more meticulous and can be based on
The corresponding of its neighbour plans motion-vector to carry out.It will be apparent to those skilled in the art that in balloon network
