Distributed Algorithm for En Route Aggregation Decision in Wireless Sensor Networks-

Abstract
Sensor networks en route aggregation decision regarding where and when aggregation shall be performed along the routes has been explicitly , implicitly studied extensively. However, existing solutions have omitted one key dimension in the optimization space, namely, the aggregation cost. In this paper, focusing on optimizing over both transmission and aggregation costs, we develop an online algorithm capable of dynamically adjusting the route stru ....etc

Impact of Node Mobility on Routing Protocols for Wireless Sensor Networks
G. Santhosh Kumar, M.V. Vinu Paul and K. Poulose Jacob
Abstract”
1
Wireless sensor networks monitor their
surrounding environment for the occurrence of some
anticipated phenomenon. Most of the research related to
sensor networks considers the static deployment of sensor
nodes. Mobility of sensor node can be considered as an
extra dimension of complexity, which poses interesting
and challenging problems. Node mobility is a very
important aspect in the des ....etc

Connected Sensor Cover: Self-Organization of Sensor Networks for Efficient Query Execution (Java)
IEEE/ACM Transactions on Networking, Vol. 14, No. 1

Abstract:
Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execution of such queries. Any reduction in communication cost would result in an efficient use of the battery energy, which is ....etc

Abstract”
In this letter, we analyze a class of Opportunistic Power Allocation (OPA) and sensor selection schemes for parameter estimation in wireless sensor networks. In all cases, only sensors experiencing favorable conditions participate in the estimation process by adjusting their transmit power on the basis of local Channel State Information (CSI) and Residual Energy Information. We address a number of classical problems: the minimization of distortion and transmit power, or the enhancement of network lifetime. Furthermore, we deri ....etc
