Wireless Sensor Networks (WSN) consists of independent sensors distributed across different locations, which are used to continuously record the environmental or physical conditions. The recorded data will be passed through the network from a sensor to a main location. Sensors life time is based on the battery power. Lower the battery power leads to decrease in lifetime for a sensor. It is important...
The reliable transmission of information is an inherently difficult and unpredictable task for LEACH-based networks. This is due to their adoption of centralized data exchange points which are expected to deliver data transmission reliability without being compromised by increasingly high rates of energy consumption. Given that this is a goal made more difficult by the constraints intrinsic to WSNs,...
Wireless Sensor Network (WSN) performs energy extensive tasks and it is essential to rotate sensor nodes frequently so that Cluster Head selections can be made efficiently. In this paper, we aim to improve the lifetime of sensor network by using LEACH based protocols and efficiently utilizing the limited energy available in these sensor nodes. In sensor network, the amount of data delivered at the...
Energy efficiency and data reliability have always been the key problem in WSN. In this paper, firstly, a selection of cluster head algorithm is designed which is able to detect the energy change of nodes, rapidly ascertain new cluster head, and avoid excessive energy consumption between cluster head and cluster nodes. Secondly, differentiated service is introduced in our algorithm which makes achieve...
In the last few years, wireless sensor networks have gained a lot of interest in the research field. WSNs consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing protocols have been proposed for WSNs. Most of the hierarchical algorithms proposed for WSNs concentrate mainly on maximizing the lifetime of the network by trying to minimize the energy consumption,...
