Given the fact that LEACH protocol didn't take the residual energy of nodes into account when choosing the cluster heads, which may result in the node with rather low energy to be chosen as a cluster head. Thus, it will cause the cluster created by this low-energy node to be dead at an early stage, which wastes the whole network's resource. Here in this paper, we introduced an energy factor when choosing...
This paper advice the modified Geographical energy aware routing in WSN. In which separation of the sensor nodes based on their location given by the node electronics using GPS, into certain regions are classified. Sink node (base station) is established away from the sensing region and a gateway node at the middle of sensing region. If the distance of sensor nodes from sink node and gateway node...
In a Wireless Sensor Network (WSN) hundreds of tiny sensors with limited resources are accommodated to sense the information from the field. Transfer of gathered information from the sensing field to the base station must be done in proficiently to sustain the network longer. Clustering of sensor nodes is one way to achieve this goal. This paper introduces an Energy Efficient clustered routing protocol...
Wireless sensor networks for existing energy consumption of each node in the uneven defect, combined with PEGASIS protocol, the first choice from the cluster, cluster formation, cluster routing and other aspects of LEACH protocol has been improved. Through theoretical analysis and simulation experiments to verify the performance of the protocol, and compared with the LEACH protocol. The results show...
Recently, wireless sensor network is widely used. The deployment of WSN in the field, however, is still restricted due to limited energy supply, limited computing power, limited buffer size, and packet delay. In this paper we present a new cluster model and polling protocol integrating the schedule polling and low power listening scheme. The new clustering approach allows short routing between the...
Wireless sensor networks have become one of the most tempting networking technologies since it can be deployed without the need of a communication infrastructure. In general, there are some major concerns with this technology. That is, sensor node should have a long lasting system lifetime. And the system should keep the livability of nodes in a received level during the using process. In such systems...
Due to the limited energy of wireless sensor networks (WSN), lots of research works have been done with topology algorithm in WSN. To solve the problem of the unbalanced energy consumption and improve the life circle, this paper proposes an Improved Energy Efficient Unequal Clustering (IEEUC) algorithm based on node degree, the clusters closer to the base station have less members than the farther...
