In spite of various constraints present in Wireless Sensor Networks (WSN), it has become popular in various application domains which need useful information. Among these constraints, energy conservation is the most important aspect. One of the known strategies to save energy and to prolong the lifetime of the WSNs is topology control. In this paper, a reliable energy-efficient topology control algorithm in wireless sensor networks is proposed.

Consumption of energy is one of the major problems in wireless sensor network, as sensor nodes driven on battery power. Therefore, it is intended to minimize the power consumption by putting the wireless interface of the sensor nodes in low power sleep mode. Wireless sensor networks constructed with hundreds and thousands of wireless sensor nodes and they deployed to solve different problems of our life

In the study of wireless ad hoc and sensor networks, clustering is an important research problem as it aims at maximizing network lifetime and minimizing latency. A large number of algorithms have been devised to compute “good” clusters in a WSN but few papers have tried to characterize these algorithms in an analytical manner. In this paper, we use a local world model to understand and characterize the functioning of three tree based clustering algorithms.

Preserving energy or battery power of wireless sensor network is of major concern. As such type of network, the sensors are deployed in an ad hoc manner, without any deterministic way. This paper is concerned with applying standard routing protocols into wireless sensor network by using topology modified by neural network which proves to be energy efficient as compared with unmodified topology. Neural network has been proved to be a powerful tool in the distributed environment.

WSN's present a new challenge in current research works due to their unlimited potential. Sensor nodes operate with limited battery power, which is seldom replaced or recharged. So, energy utilization is an important constraint in designing routing protocols in WSN. In this paper, we proposed an event based hierarchical cluster based routing algorithm with the objective of reducing the energy consumption for creating the routing topology .

There are many challenges involving WSN design such as the energy resources optimization, the robustness and the network coverage. We address here the problem of energyefficient topology design. A well designed dynamic topology and efficient routing algorithms may allow a large reduction on the energy consumption. As such type of network, the sensors are connected in an ad-hoc manner, without any deterministic way

Abstract Due to the limited processing power, and finite power available to each sensor node, regular ad-hoc routing techniques cannot be directly applied to sensor networks domain. Thus, energy-efficient routing algorithms suitable to the inherent characteristics of these types of networks are needed. However highly efficient data centric model of routing will improve the longevity of the network.
