Controlling power utilization in the residential area is one of the major challenges in the smart grid (SG). Demand response (DR) has played a vital role in energy management and improved it with the involvement of residential consumers who participate in such programs from utilities for scheduling their appliances to the off peak hours. In this paper, we have proposed a world-wide adaptive thermostat...
This paper presents an incremental cooperative communication scheme for a buffer-aided three node relay network consisting of a source, an Amplify and Forward (AF) relay and a destination. We consider the presence of direct link and propose a scheme which is based on the concept of packet diversity rather than link diversity. The scheme is designed in such a way that packets that experienced bad channel...
Underwater wireless sensor networks (UWSNs) arouse as a better alternative of underwater wired instruments for data gathering. Acoustic signals offer low bandwidth and UWSNs faces low reliability, high delay and high energy consumption issues. Moreover, energy holes creation decreases network performance in terms of energy and throughput. The design of routing protocols which considers these challenges...

In Wireless Sensor Networks (WSNs), there are two major factors which minimize the performance of the network. The one is the void hole which occurs in a particular region due to unavailability of forwarder nodes. The other one is the presence of energy hole near the sink due to death of the nodes. An optimum transmission strategy is the need in this case in order to maximize the network lifetime...
