Wireless sensor networks (WSNs) give us the opportunity to monitor a variety of real time environmental conditions and it helps to make our lifestyle modernized. Usually, every sensor node (SNd) consists of a small battery which is difficult to recharge. The main problems with this WSN are to provide longer lifetime and to maintain the energy consumption level equal for every SNd. When SNds are deployed...
Energy efficiency is resent issue in wireless sensor network (WSN). Hierarchical routing or Clustering is best solution for reducing energy consumption in WSN. LEACH (Low energy adaptive clustering hierarchy) is good hierarchical protocol. There are many protocols introduced based on LEACH but still have issue of energy efficiency. Lots of research is going on CH (cluster head) election algorithm,...
Wireless Sensor Networks (WSNs) typically aggregate sensed events into a sink by Continuous Monitoring (CM) or Event-Detection (ED). Cluster heads receiving and sending aggregated data have a difficulty in maintaining traditional cluster-based WSNs due to the energy hole problem, which leads to faster energy depletion around the sink. This paper shows how reporting frequency to the sink can be controlled...
This paper presents an improved version of LEACH protocol which aims to reduce energy consumption within the wireless sensor network and prolong the lifetime of the network. This paper improves LEACH protocol by improving the election strategy of the cluster-head nodes based on remaining energy of sensor nodes, distance from base station and the number of consecutive rounds in which a node has not...
The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency,...
Energy Efficient Routing is a crucial issue in Wireless sensor networks (WSNs). This paper proposes a novel algorithm, Parametric Protocol for Energy Efficient Cluster Head Selection (PPEECS) in WSN, which consists of two phases; Region formation phase and Cluster Head (CH) selection phase. In prior phase we divide the network into several regions depending upon node density distribution. The later...
On the basis of analyzing the Low-Energy Adaptive Clustering Hierarchy (LEACH), a clustering routing algorithm for Wireless Sensor Network (WSN) based on ant colony algorithm (ACA) is proposed in this paper. We applied the ACA to inter-cluster routing mechanism and looked for the best path from cluster heads to base station. Thanks to the algorithm, the transmission of information, for the cluster...
