Signal routing
View Patent ↗A method for routing communications in a communications system comprising a plurality of communication nodes, each node being capable of transmitting signals to and receiving signals from one or more other nodes, and including a first node, a second node and a plurality of other nodes; the method comprising selecting a route for communications from the first node to the second node by way of at least one of the other nodes on the basis of mobility characteristics and/or energy characteristics of each of the other nodes.
1. A method for routing communications in a communications system, the method comprising:
providing a plurality of communication nodes in the communications system, each node transmitting signals to and receiving signals from one or more other nodes, and including a first node, a second node and a plurality of other nodes;
selecting a route to communicate from the first node to the second node by way of at least one of the other nodes based on energy characteristics of each of the other nodes; and
selecting a route to communicate from the first node to the second node by way of at least one of the other nodes based on mobility characteristics of each of the other nodes, wherein the energy characteristics include the energy available to each of the other nodes.
2. A method as claimed in claim 1 , further comprising:
routing communications from the second node to the first node by way of at least one of the other nodes on the basis of energy characteristics of each of the other nodes.
3. A method as claimed in claim 2 , further comprising:
performing said routing of communications from the second node to the first node independently of routing of communications from the first node to the second node.
4. A method as claimed in claim 3 , wherein the mobility characteristics include the current velocity of each of the other nodes.
5. A method as claimed in claim 4 , wherein the mobility characteristics include the current direction of each of the other nodes.
6. A method as claimed in claim 1 , wherein the energy characteristics include the energy available to each of the other nodes for transmission of signals to other nodes.
7. A method as claimed in claim 1 , wherein the energy characteristics include the power required for transmission of signals to those other nodes.
8. A method as claimed in claim 7 , wherein the power is determined as a function of the distance between the nodes.
9. A method as claimed in claim 1 , wherein the energy characteristics include the energy available to each of the other nodes for reception of signals from other nodes.
10. A method as claimed in claim 9 , wherein the energy characteristics include the power required for reception of signals from those other nodes.
11. A method as claimed in claim 10 , wherein the power is determined as a function of the distance between the nodes.
12. A method as claimed in claim 1 , wherein the signals are wireless signals.
13. A method as claimed in claim 1 , wherein the signals are radio signals.
14. A communications system, comprising:
a plurality of communication nodes, each node configured to transmit signals to and receive signals from one or more other nodes, and including a first node, a second node and a plurality of other nodes;
a router configured to route communications from the first node to the second node by way of at least one of the other nodes based on available energy of each of the other nodes; and
a terminal unit configured to select a route to communicate from the first node to the second node by way of at least one of the other nodes based on mobility characteristics of each of the other nodes.
15. A communication system as claimed in claim 14 , wherein the router is configured to route communications from the first node to the second node by way of at least one of the other nodes based on a mobility of each of the other nodes.
16. A communication terminal to operate as a first node in communications system comprising a plurality of communication nodes, the communication terminal comprising:
a router configured to route communications from the first node to a second node by way of at least one of other nodes based on available energy of each of the other nodes, wherein each node in the communications system is configured to transmit signals to and receive signals from the other nodes, and the communications system include the second node and the plurality of other nodes; and
a terminal unit configured to select a route to communicate from the first node to the second node by way of at least one of the other nodes based on mobility characteristics of each of the other nodes.
17. A communication terminal as claimed in claim 16 , wherein the router is configured to route communications from the first node to the second node by way of at least one of the other nodes based on a mobility of each of the other nodes.
18. A communications system, comprising:
a plurality of communication nodes, each node for transmitting signals to and for receiving signals from one or more other nodes, and including a first node, a second node and a plurality of other nodes;
routing means for routing communications from the first node to the second node by way of at least one of the other nodes based on available energy of each of the other nodes; and
terminal means for selecting a route to communicate from the first node to the second node by way of at least one of the other nodes based on mobility characteristics of each of the other nodes.
