Clustering in wireless sensor networks improves lifetime of the network by load distribution, data aggregation and use of clusterheads to efficiently route messages to the central gateway. Parameters governing creation of optimal clusters are often numerous and domain-specific. The challenges increase with mobile nodes due to faster temporal change in one or more parameter values like speed and distance...
Prolonging life time is the most important designing objectives in wireless sensor networks (WSN). In WSN the total amount of energy is limited, how to make best use of the limited resource energy is a very important aspect in research of WSN. In this paper we provide a method for determining the optimal number of cluster head for homogeneous sensor networks deployed in different scenario using a...
Sensor networks are widely used in environmental exploration, military systems, and factory production monitoring. They usually have limited battery source and link bandwidth. Many algorithms have been proposed till now that considered three functional components namely data gathering (sensing and acquisition), data transport and data analysis (processing). In general power is consumed whenever a...
The paper considers the algorithm NLU for distributed (vector) parameter estimation in sensor networks, where, the local observation models are nonlinear, and inter-sensor communication is imperfect, in the sense, that the network links fail randomly and inter-sensor transmission is quantized. The paper introduces the class of separably estimable observation models, which generalizes the notion of...
