Abstract: A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. Energy efficiency is the important key for WSN. To lower the energy consumption, the network is divided into several clusters in cluster routing algorithm LEACH (Low Energy Adaptive Clustering Hierarchy). Even though clustering provides energy efficiency, but uneven load distribution still occurs in general. In this paper an approach is presented which divides the deployment region into sub-regions and thereby uniformly distributing the load among the sensor nodes. Different shapes are considered for dividing the deployment region into equal sub-regions.

Abstract: This paper concentrates on predicting and removing the major cause of railway accidents, that is, head-on collisions on the same track. For this purpose we are using advanced technology to identify train positions, detect collision as well as the points where collisions may occur. The primary goal of this paper is to provide an anti-collision safety device for vehicles travelling on tracks, even without any driving personnel, that is to say, a device which itself can estimate risks and react in consequence. This ensures that if any collision is likely to occur, then this system will help to avoid collisions by giving an alarm in time and actuating emergency brakes if required. The goal of this work is to design and implement a cost effective and intelligent full-fledged microcontroller and wireless based Train Anti Collision System to successfully prevent the train collisions. It aims at efficiently integrating into the existing signaling system implemented in Indian Railways and avoid
