摘要：Sensor networks have inspired tremendous research interest in recent years. Sensor networks consists of thousands of server nodes, deployed either randomly or according to some predefined statistical distribution, over a geographic region of interest. Heterogeneous wireless sensor network can be used in variety of fields like battlefield surveillance, in furnaces for measuring temperature, in wildlife habitat for tracking endangered species etc. In all these applications it is necessary to provide QOS which can be provided by ensuring coverage and connectivity for a longer time. In this paper we have devised a new algorithm Improved coverage and connectivity preserving routing protocol in which we have designed the network where gateway is placed near to sink and cluster heads are placed in center near to gateway as well as those nodes are selected as cluster head and gateway which have high residual energy and maximum no. of neighbors
