METHOD FOR MAXIMIZING RESIDUAL POWER ALONG ROUTE IN WIRELESS NETWORK AND WIRELESS NETWORK INCLUDING MULTIPLE NODES OPERATED BY BATTERY

摘要

PROBLEM TO BE SOLVED: To solve the problem caused by an ad-hoc wireless communication network including multiple nodes.

SOLUTION: Each node maintains a routing table. The routing table is constructed by broadcasting route request packets from a source node. The request packet includes the address of a destination node. Intermediate nodes in the network receiving the request packet determine power and delay costs associated with the intermediate node participating in the route. If the costs are less than a threshold value, then the intermediate node participates in the routing of packets for other nodes. The intermediate nodes then send a reply packet back to the source node. The reply packet includes the intermediate node addresses, as well as the power and delay costs. The source can thus construct the routing table. The source node can select a specific node for transferring application data packets based on either the power cost, the delay cost, or both costs.
