BATTERY LIFETIME AND SIGNAL BASED ADAPTIVE ROUTING AND APPARATUS FOR MOBILE AD-HOC NETWORKS

摘要

PURPOSE: A mobile ad-hoc network routing method in consideration of a remaining battery amount and signal stability of a communication node is provided to set a routing path in consideration of a remaining battery amount of intermediate/receiving nodes that are involved in a multi-hop path, thereby extending a lifetime of a mobile ad-hoc network. CONSTITUTION: When an RREQ(Routing Request Message) control packet is received, an intermediate node updates a routing entry of a self node as initializing data and driving a routing process(S601,S602), and confirms a UDP(User Datagram Protocol) receiving port of an IP datagram received from a UDP upper layer(S603,S604). If the UDP receiving port is a port 654, the intermediate node confirms whether RREQ link quality exceeds a restricted value(S605) and confirms whether a remaining battery amount is sufficient(S606). If so, the intermediate node decides whether an originating sequence number of the RREQ control packet is bigger or identical with a sequence number value of the routing entry and whether the number of hops is less than the number of hops of the routing entry(S607,S608). If so, the intermediate node adds a reverse path to a routing table.
