IRJET-Role of Clustering in Achieving Energy Efficient Coverage in Wireless Sensor Network : A Short Review (original) (raw)

Wireless Sensor network (WSN) comprises of tiny sensor nodes with very limited initial energy and are deployed in sensing area of particular interest to fetch necessary environment data and sending it back to end user via base station. One of the major issue in WSN is energy efficient coverage in which major goal of routing protocol is to observe every possible physical space without any loss of data due to lack of energy or power in sensor node. Such situation may occur due to over burden on nodes when unbalanced clusters are formed leading to extra communication overhead. In this Paper we are discussing overview of WSN in first half and in second half of paper energy efficient coverage problem along with some popular routing protocol covering this issue has been discussed.
