Mobility Aware Mac Protocal with Delay and Relay Node Selection for Clustered Mobile Wireless Sensor Networks

Abstract

Power and delay is a vital and sensitive concern in the routing protocols, Wireless Sensor Networks (WSNs).The wireless sensor nodes are broadcast in particular place of the environment to identify events and establish WSN. These wireless sensor nodes have confines such as memory, power and computational competence. Since medium Access Control sub layer controls transmissions of the media and collisions, it has significant impact in reducing energy consumption and increasing the channel s efficiency. Therefore, the medium Access Control sublayer plays an vital role in wireless sensor network. By allocating channel duty, media access control sub-layer can reduce collisions; these measures can reduce energy usage and increase the productivity of the channel. This thesis, an improved MAC protocol is proposed based on clustering technique. Using a multi-layered approach, this technique is intended to diminish competition and traffic in the network. The proposed algorithm consists of two steps including clustering and data transferring of each cluster. The proposed approach can significantly reduce collision, sleep-delay and idle listening. In order to appraise the suggested algorithm computer simulation approach is used. The consequences of reproduction show that the enactment of the suggested protocol is more effective than other present protocols like MLMAC in relationships of the following features: number of positively sent packets, number of collision, energy consumption and sleep delay. newline
