This paper presents a restricted-area-based localization algorithm (RAL) for wireless sensor networks (WSN), in which radio connectivity and principle of perpendicular bisectors are used to provide a lower estimation error than some of restricted-area-based localization algorithms. In the RAL algorithm, anchor nodes can transmit beacon signals at different power levels, which divide the possible transmission...
Energy balance is an important performance index in the design of routing algorithm for wireless sensor networks. A swarm intelligence optimization based routing algorithm for wireless sensor networks is proposed, whose kernel idea is taking less hop numbers into consideration and choosing the nodes with less pheromone as next hop to avoid some nodespsila prematurely exhausting their energy because...
