In this paper, we present an energy efficient, scalable, and distributed node disjoint multipath routing algorithm for wireless sensor networks (WSNs). The proposed algorithm, the multipath energy-aware routing protocol (MERP), adjusts traffic flows via a novel load balancing scheme. The MERP has a higher average node energy efficiency, lower control overhead, and a shorter average delay than those...
Time synchronization is essential in sensor network applications such as object tracking, consistent state updates, duplicate detection and temporal order delivery. In addition, reliability issues and fault tolerance in sophisticated sensor networks have become a critical area of research today. This paper proposes a lightweight fault tolerant time synchronization (LFTTS), an extension of fault tolerant...
