ABSTRACT

The main thing we work on is Wireless Sensor Networks (WSNs) which contain numerous sensor nodes with limited power resources, which report sensed data to the Base Station (BS) that requires high energy usage. We want to let the battery live as long as we can, as the cost of changing batteries of nodes is high and also difficult. So, we use efficient protocols which improve the way the sensors use to send and receive sensed data to BS on other hand, nodes closer to the base station are exploited as they have to spend additional energy in relying on data of faraway nodes. This brings in the idea of implementing blanket coverage in heterogeneous wireless sensor networks for the internet of things. In this paper, we first test Distributed Energy Efficient Clustering (DEEC), Developed DEEC (DDEEC), Enhanced DEEC (EDEEC), Threshold DEEC (TDEEC), and Improved DEEC Protocol (IDEEC) under several different scenarios. We observe thoroughly the performance based on stability period, network lifetime, and throughput. EDEEC and TDEEC perform better in all heterogeneous scenarios containing variable heterogeneity in terms of lifetime, however, TDEEC is best of all for the stability period of the network. IDEEC is better than DDEEC in terms of Overhead, but TDEEC is the best. However, the performance of DEEC and DDEEC is highly affected by changing the heterogeneity parameters of the network.
