Based On The Dsr Protocol In Ad Hoc Networks Energy Balance Routing Protocol

Mobile Ad Hoc network is a kind of self-organized network which is multi-hop, distributed and un-center. It works with out any preexisting infrastructure, has strong resistance of being destructed and convenience of forming. So Ad Hoc network is widely used in military, rescue, detect and personal communication. However, as the nodes in Ad Hoc network is extremely power-limited, the research of power-aware routing protocol becomes a popular issue.At present, most power-aware routing protocols pursuit to minimize the total power consumption of transmission or maximize the lifetime of the network, but omitted the other factors of the network which reduced the other performances of network. Thus, we proposed the PAB-DSR (Power-Aware and Balanced Dynamic Source Routing Protocol) routing protocol. This routing protocol takes into account of four factors, lifetime of the node, routing load, routing hops and the delay of network. Also, it provides every factor with a cost function, and then put them together to create a balanced cost function. The algorithm prefers to elect the route which has the minimal cost, so as to lengthen the lifetime of the network and keeps balance on other performances of the network. According to the algorithm, this paper designed the data structures and route discovery phase.Moreover, this paper realized the PAB-DSR protocol on the environment of NS2. And then, made simulation experiments on DSR and PAB-DSR routing protocol. Compared with the DSR protocol, the result of the simulation indicates that PAB-DSR protocol can obviously lengthen the lifetime of the network and improves on packet delivery ratio, average end-to-end delay and routing load.
