Simulation Results

Wireless sensor networks (WSNs) have gained worldwide attention in recent years. Since WSNs can be conveniently deployed to monitor a given field of interest, they have been considered as a great long-term economic potential for military, environmental, and scientific applications and so forth. One of the most active areas of research in WSNs is the coverage which is one of the most essential functions to guarantee quality of service (QoS) in WSNs. However, less attention is paid on the heterogeneity of the node and the energy balance of the whole network during the redeployment process. In this work, the energy balanced problems in mobile heterogeneous WSNs redeployment have been analyzed. The virtual force algorithm with extended virtual force model is used to improve the QoS of the deployment. Furthermore energy model is added to enhance or limit the movement of the nodes so that the energy of nodes in the whole WSNs can be balanced and the lifetime of the networks can be prolonged. The simulation results verify the effectiveness of this proposed algorithm.

While wireless sensor networks are increasingly equipped to handle more complicated functions, these battery poweredsensors which used in network processing, use their constrained energy to enhance the lifetime of the network especially in a heterogeneous settings. Clustered techniques have since been employed to optimize energy consumption in this energy constrained wireless sensor networks. In Classical clustering protocols, equal energy is assigned to all nodes andthey cannot take full benefit of the presence of node heterogeneity. SEP, a heterogeneous-aware protocol is used to prolong the time interval before the death of the first node which is crucial for many applications where the feedback fromthe sensor network must be reliable. The performance of SEP in comparison to LEACH Protocol is analyzed in this paperwhose goal is to increase the stable region and as a result decrease the unstable region and improve the quality of thefeedback of wireless sensor network, in presence of heterogeneous nodes.
