Optimal Mobility based Data Gathering Scheme for Life Time Enhancement in Wireless Sensor Networks

The Wireless Sensor Networks (WSN) is widely used in gathering applications. Data gathering is the main operation and this data process uses the continuous monitoring ability of WSNs. The main constraint of WSN is its energy efficiency and data gathering operation highly influences the lifetime. Multiple researches has been performed to overcome this issue of lifetime of WSNs. In the existing research EDCMS has been used along with Maximum capacity path Routing protocol. Though this method was found to be effective in terms of data gathering, the waiting time of the nodes, the deliver the gathered data to the Dynamic Sink influenced the throughput of the network. For this purpose, Optimal Mobility based Data Gathering method (OMDG) with Time-varying Maximum Capacity Path Routing protocol (TMCP) is proposed. Here CHEF was used for Clustering and, multiple dynamic sinks are used to gather the gathered data within the cluster in order to reduce the waiting time. The gathered data is delivered to the cluster head and this increases the life time of WSNs. Simulation was done through NS-2 and OMDG is compared with the multiple existing methods and results has proven to better.
