Comparative study on WSN homogeneous and heterogeneous architecture WSN- An Architecture Study

Abstract

An important thing in managing wireless sensor networks is its lifetime, Here in this research work it has been proposed with a data centric approach to increase the lifetime by studying various parameters used in the wireless sensor networks. As by studying on various parameters, the first one by focusing on the optimized routing technique which helps to avoid the data traffic in wireless sensor networks. The next on is Sensors aggregation, the signals strength passed through the network was increased, thus helps to tune the performance what the end user expected out of WSN. The next parameter is by using mobile relays the lifetime can be extended. The mobile relays are very active in the performance tuning methodology, where it moves around the network very faster than any other static nodes.

These mobile relays help other sensor nodes to relieve the burden it receives and face. Mobile relays have the capacity to increase the WSN twice faster. The next one is to increase its performance by deriving a new querying technique and increasing its energy and storage resources using more floating nodes.
