Energy consumption problem is considered an extremely important problem that faces the Wireless Sensor Networks (WSNs). For this reason, a lot of efficient energy protocols have been developed in order to reduce the energy consumption, as well as to prolong the lifetime of the sensor networks. The DMHT-LEACH protocol is one of these protocols. It proposes a dynamic technique for facilitating the data...
This paper emphasis on different hierarchical routing protocols in wireless sensor network. The Clustering approached is used in LEACH protocol for better communication with energy saving. The Sectoring Scheme is used in MARS approach for dividing the sensor network into different sectors. It improves reliability of an application or network. The working of both the approaches is explained in algorithmic...

A distributed and collaborative nature of wireless sensor network cause many challenges to provide security in network. Most of the outsider's attacks are prevented by encryption and authentication technology, but to control insider attacks are difficult. A malicious sensor node causes lot of packet losses, energy wastage and increase in time to reach final destination. In this paper, Enhanced Beta...
This work focusses on analyzing the optimization strategies of routing protocols with respect to energy utilization of sensor nodes in Wireless Sensor Network (WSNs). Different routing mechanisms have been proposed to address energy optimization problem in sensor nodes. Clustering mechanism is one of the popular WSNs routing mechanisms. In this paper, we first address energy limitation constraints...
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,...
In order to tackle the energy hole problem of sensor networks, the non-uniform node deployment strategy was presented recently. For achieving the expected performance of this deployment method, nodes need to transmit data to the sink node through selecting a node in the adjacent inner-region decided by the deployment strategy. Since nodes near the outer-boundary of a region will be covered by more...
Based on the analysis on the defect in LEACH including the fluctuation of the number of cluster heads and the ignorance of the node's residual energy, this paper presents a novel protocol called LEACH-B (LEACH-Balanced).At each round, after first selection of cluster head according to LEACH protocol, a second selection is introduced to modify the number of cluster head in consideration of node's residual...
This paper presents an energy aware learning automata-based routing protocol, ICLEAR, for wireless sensor network that adopts a novel approach to increase the network lifetime. This protocol is energy saver and manager both. We decrease energy consumption to increase network lifetime and manage routing discovery procedure to find best route in energy consumption by irregular cellular learning automata...
In order to achieve energy conservation in WSNs, most topology management protocols use a subset of sensor nodes for global routing. Using fewer nodes results in a reduced connectivity of the network, which eventually increases the number of routing holes. Holes in networks often cause failures in message routing due to the local minimum problem. Therefore, traditional geographic routing protocols...
A robust routing protocol is an efficient way to deal with false behaviors generated by abnormal nodes in a wireless sensor network (WSN). In this paper, we propose a dynamic adaptive and robust routing protocol for wireless sensor network based on probability control algorithm (PCA). PCA is one of stochastic optimistic methods; it converts routing quality evaluation information into the probability...
In this paper we investigate the behaviour of M-GeRaf, Multisink GeRaf, a data dissemination protocol for multisink wireless sensor network environments based on a geographic random forwarding routing approach. The protocol exploits the intrinsic broadcast nature of the wireless channel in order to allow a reliable and efficient data delivery to a set of data sink nodes in networks with an aggressive...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
