Power Aware Packet Routing Control in Ad-Hoc Wireless Networks
Qilian Liang, Nancy Neigus · Kluwer Academic Publishers eBooks · 2005
Most existing works on power aware packet routing are based on the remaining battery capacity. In this chapter, we make power aware routing control based on four descriptors: remaining battery capacity, packet loss requirement, distance to the gateway or next node, and size of incoming packet. We applied a fuzzy logic system to packet forward/discard decision making. Linguistic knowledge is represented using fuzzy rules, and linguistic labels are represented using membership functions. Soft decision surface is obtained for packet forwarding/discarding, and hard decision boundary is generated for the node. Comparing to the minimum battery cost routing and min-max battery cost routing methods, our method incorporates three more descriptors as well as remaining battery capacity,which makes the packet forwarding/discard decision more effective.
