Abstract: | In this paper, we propose a high performance routing protocol and a long lifetime routing protocol by considering the fact
that the bandwidth between two mobile nodes should be different when distances are different. In the high performance routing
protocol, to reduce the number of rerouting times, we take the bandwidth issue into account to choose the path with the capability
to transmit the maximum amount of data with the help of the GPS. With exchanging the moving vectors and the coordinates of
two adjacent mobile nodes, the possible link lifetime of two adjacent mobile nodes can be predicted. Subsequently, a path
with the maximal amount of data transmission can be found. With regard to our proposed long lifetime routing protocol, to
maximize the overall network lifetime, we find a path with the maximal remaining power after data transmission. With the link
bandwidth and the desired amount of data transmitted, the consumption power is computed to obtain the remaining power of a
mobile node. Accordingly, we can choose the path with the maximal predicted remaining power to maximize the overall network
lifetime. In the simulation, we compare our high performance routing protocol with the AODV and LAWS in terms of throughput,
rerouting (path breakage), and route lifetime. With respect to power consumption, we compare our proposed power-aware routing
protocol with the POAD and PAMP in terms of the overall network lifetime and the ration of survival nodes to the all nodes. |
