Low Power Routing Protocol Research For Mobile Wireless Sensor Network

With the development of technologies such as communications, embeddingcomputing, micro sensor and wireless network technology, wireless sensornetwork (WSN) has attacted attentions for its promising applications. The WSNhas been employed universally in modern agricultural, industral, academical aswell as military applications.Mobile Wireless Sensor Network (MWSN), where sensor nodes can bemovable, has been widely focused on. Mobile sensor node in MWSN cooperatewith each other and send the data to sink node which can realize data processing.Therefore, the routing protocol for network data transfer plays a crucial role inthe MWSN. Traditional MWSN routing protocols are usually power-hungry.Since the energy of a sensor node is usually limited, energy consumption is amajor problem to be coped with carefully. In this paper, the target is to reduce theenergy consumption of MWSNs by introduce a novel routing protocol.In this thesis, a low energy consumption routing protocol namedFull-Functional-Node Based Routing Protocol (FRP) is designed and evaluated.The major idea of the protocal is to use some full function nodes to collect andtransmit sensing data. Moreover, an algorithm, whose aim is to optimize thedistribution of full function nodes, is proposed. The algorithm divides thenetwork into a finite number of small sub-regions according to the probability ofthe presence of mobile nodes. In the protocol, the iteration makes sure that allmobile sensor nodes can be connected to at least one full function node. Finally,based on MATLAB platform, the FRP is simulated and compared to LEACH-M.The simulations are carried out under both gaussian distribution and uniformdistribution scenarios respectively. Simulations concludes that the FRP canreduce network energy consumption efficiently.
