Performance investigation of heterogeneous algorithms in WSNs

In this paper, we consider the problem of increasing the lifetime of a target monitoring sensor network. The network consists of two types of sensor nodes, i.e. normal and advance nodes with adjustable sensing ranges that is deployed to monitor a set of targets. An advance node consists of a times more energy than a normal nodes. A sensor can be in one of the three states namely active, deciding and sleep state. We propose a mechanism to increase the lifetime of a sensor network using a heterogeneous energy model. The simulation results demonstrate that the proposed method improves the wireless sensor network lifetime significantly over the ALBPS and ADEEPS methods. We compare the results of the proposed method with that of the ALBPS and ADEEPS methods because these methods have better performance among all the existing methods of the monitoring methods.
