Wireless sensor networks (WSN) are spatially distributed micro sensor systems. A WSN with large number of tiny nodes can be effectively used for gathering data in variety of environments like civil or military applications. WSN is a power constrained system, since nodes run on limited power batteries which shorten the life time of the system. Prolonging the life time depends on efficient commun...

Wireless communication protocols are centric to Wireless Sensor Network (WSN) applications. However, WSN protocols are prune to defects, even after their field deployments. A convenient tool that can facilitate the detection of post-deployment protocol defects is of great importance to WSN practitioners.

Wireless Sensor Networks (WSN) are characterized by the dense deployment of sensor nodes that continuously observe physical phenomenon. Due to high density in the network topology, sensor observations are highly correlated in the space domain. Furthermore, the nature of the physical phenomenon constitutes the temporal correlation between each consecutive observation of a sensor node. These spat...

Wireless Sensor Network (WSN) consists of a large number of sensor nodes to detect some physical phenomena. To design a WSN it is necessary to identify the major issues or the main metric parameters of WSN, which are network lifetime, data gathering, and security. These parameters effect on the overall performance of WSN. To enhance the performance of that network in this paper, we present a su...

Wireless Sensor Networks (WSN) find its applicability from military to medical fields. Many of these applications requires node mobility. One of the systematic technique to incorporate efficient utilization of constrained resources in WSN is through clustering and also mobility aids to avoid hotspots. Clustering is a process in which the randomly deployed nodes of WSN are divided into non-overl...
