ERPT based reliable data dissemination in Wireless Sensor Network

Reprogramming is a critical problem in Wireless Sensor Network (WSN). Each cluster head receive a different form of data among individual sensor nodes and from other neighborhood cluster head, which leads to loss in accuracy of data. Multihop transmission to the base station will cause loss in actually sensed data. In this paper, Enhanced Reprogramming Technique (ERPT) is to maximize accuracy of data with minimum energy utilization. In our approach, two levels of aggregations are performed. One is an intra-cluster aggregation within the cluster head and inter-cluster head aggregation are performed from one cluster head to another cluster head. It improves network lifetime by reducing the amount of traffic among individual sensor nodes to the base station because sensor nodes are resource constraints. Increasing number of nodes among sensor network will maximize the accurate data, but it leads to more energy consume. This will be improved by enhanced reprogramming. The proposed technique addresses the scalability issues with minimized energy consumption compared to traditional approaches.
