Wireless sensor networks consist of a large number of sensor nodes that combine physical sensing (e.g. temperature, light) with networking and computation capabilities. Sensors are small entities where conservation of battery power is a major design factor. In-network processing, such as aggregation, eliminates similar/redundant data and decreases the number of communication messages to be sent to...
In order to increase the network lifetime, scalable and energy-aware routing protocols are very essential for Wireless Sensor Networks (WSNs). In this paper, we propose a heterogeneity-aware Multi-hop Centralized Energy Efficient Clustering (MCEEC) protocol for routing in WSNs. Operation of MCEEC is based upon the advanced central control algorithm, in which Base Station (BS) is responsible for the...
Cluster based routing technique is most popular routing technique in Wireless Sensor Networks (WSNs). Due to varying need of WSN applications efficient energy utilization in routing protocols is still a potential area of research. In this research work we introduced a new energy efficient cluster based routing technique. In this technique we tried to overcome the problem of coverage hole and energy...
From energy conservation perspective in Wireless Sensor Networks (WSNs), clustering of sensor nodes is a challenging task. Clustering technique in routing protocols play a key role to prolong the stability period and lifetime of the network. In this paper, we propose and evaluate a new routing protocol for WSNs. Our protocol; Divide-and-Rule (DR) is based upon static clustering and dynamic Cluster...
We incorporate the clock skew in the message exchange mechanism, without which the clock synchronization problem remains practically unsolved. For the offset-only case, we determine the ML estimators through a simple application of convex optimization, alleviating the need for the graphical search mentioned. We also propose estimators that outperform the ML estimators in terms of MSE. For the joint...
