A novel multipath routing protocol for wireless sensor networks is proposed. The protocol constructs multiple paths based on residual energy of the nodes in the network and allows the source node to make energy based decisions to select a path for data transmission from the set of discovered paths. Using alternative paths for routing data packets incorporates load balancing in the network which maximizes...
Wireless sensor networks have sensor nodes that communicate with each other for transmitting the data and thus consume its most of the energy during this transmission. They are battery exhaustive and the battery life is limited. There is need to minimize this energy consumption and as a result extend the overall network lifetime. A novel approach is proposed in this paper that makes use a hybrid combination...
Energy efficient clustering has gained enormous attention in wireless sensor networks (WSNs) in the last few decades. In clustered WSNs, cluster heads (CHs) bear some additional load such as data sensing, data aggregation and sending data to base station. However, improper formation of clusters can overload some CHs and resulting higher energy consumption that may lead to deaths of such CHs. Load...
In the energy-constrained wireless sensor networks (WSNs), clustering is an efficient technique to minimize the energy consumption of the sensor nodes. But, the clustering algorithms for WSNs with a static sink frequently suffers from uneven energy consumption problems, where cluster heads (CHs) further away from sink consume more energy in a single hop communication, with the CHs sending its data...

Energy is a critical issue for maintaining the WSNs. In this paper we propose a distributed chain-based routing scheme for energy efficient WSNs. In order to balance the distance between the nodes, the entire area containing the network is partitioned into equal size sub-areas. The nodes in each sub-area are connected into a chain using an algorithm similar to the minimum spanning tree algorithm....
This paper considers a cluster-based wireless sensor network (WSN) where each sensor node takes turn to be cluster head. The main function of the cluster head is to oversee the communication within and between clusters while the remaining sensor nodes are involved in sensing of the surrounding environment. We address the sensor utilization problem where non-cluster head nodes in a cluster make decision...

Clustering is an effective approach to hierarchically organizing network topology and to prolong the lifetime of a wireless sensor network.

Most of the researches in this field has focused...
