Investigations on Design Aspects of Power Aware Routing Protocol in Wireless Sensor Networks

Abstract

This thesis aims to investigate for WSN routing protocols to consider the energy and power level of sensor nodes through the organization of routing processes in order to increase lifetime of the network and reduce the energy consumption ratio of wireless sensor nodes. The proposed work relates to incorporating the investigation on power consumption and energy optimization in wireless sensor networks and ad hoc network environment by ensuring the power consumption of the intermediate nodes in the network. The proposed protocol simulated on the computer system using QualNet and Matlabsimulation software s. newlineThis thesis includes the Quality of Service (QoS) for performance analysis of more than eighteen MANET and WSN routing protocols: reactive routing protocol like OLSR, on demand routing protocols DYMO,AODV and DSR and which are based on IEEE 802.11, and hybrid protocol ZRP. The implementation was achieving over a real practical designed scenario considering some fundamental metrics with MAC layer and physical layer models, in order to investigatethe performance of effectiveness of wireless routing protocols. Performance is investigated and compared on the performance measuring metrics of application layer like Packet Delivery Ratio (PDR), Throughput, E-E Delay, Jitter, Network layer based performance metric Hop Count,Power consumed in transmit, Receive and idle/sleep modes and Average Waiting Time of messages and MAC layer based performance metrics RTS, CTS, ACK packet send, Broadcast Received, Broadcast Received Clearly, etc with varying number of nodes, mobility with constant bit ratio(CBR) traffic load, and network node design. newlineMobile Ad hoc Network (MANET) and wireless sensor network (WSN) is a collection of nodes (mobile) temporarily connected in order to provide data communication. In order to provide efficient and reliable path between a pair of nodes, a routing protocol is used. Various routing protocol are available in literature such as table driven, on demand and hybrid. All these routing protocols are a
