Minimum Energy Consumption Routing Protocol in Multi-Rate Non-Infrastructure Wireless Network

Abstract

The wireless ad hoc network and the sensor network are characterized by rapid deployment; dynamic, multi-hop topology; and self-organization without typical infrastructure support. Other important issues are that the fluctuant bit rates cause the power consumptions, throughputs, and transmission times to vary. In addition, shared media only allow one couple of nodes to transmit at the same time, so other nodes must wait. We formulate this as a minimum energy consumption problem in a multi-rate, multi-hop wireless network, utilizing energy-aware routing and a passive mode strategy with Ready to Send (RTS), Clear to Send (CTS), and acknowledge (ACK) control frames. The numerical results show that for various numbers of MHs and packet sizes the energy consumption rate is lower than the original minimum hop routing protocols, such as Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Temporally-Ordered Routing Algorithm (TORA), and multi-rate aware sub layer (MAS) [26]. The delay is also lower than these methods.
