Rumor Routing is one of the routing algorithm categories in wireless sensor networks which is well extended and optimized in the recent years. Common principal ideas in all rumor routing algorithms are conjunction of query-agents with the traversed path of event information propagator agents in the network. In this paper we propose a new method to reduce the number of routing agents to consequently...
The smart grid is a new advanced electrical network promoted by the government to address environmental sustainability, energy generation, distribution and consumption efficiency issues. As one of the enabling technologies, Advanced Metering Infrastructure refers to systems which measure, collect and analyze energy usage, and interact with advanced devices such as smart meters through various communication...
Greedy forwarding fails due to void area, termed a hole, where no nodes can be deployed in realistic wireless sensor networks. This is known as the local minimum problem. Several schemes have been recently proposed to solve this problem. However, they have the problem that nodes, which are adjacent to the hole, have to maintain hole boundary information and an increase in hop counts due to additional...
Limited bandwidth remains a pressing issue for wireless sensor networks (WSNs) due to the half-duplex property of the sensor radio and the broadcast nature of wireless medium. Designing multi-channel MAC protocol attracts the interest of many researchers as a cost effective solution to meet the higher bandwidth demand for the limited bandwidth in WSN. In this paper, we present a scheduled-based multi-channel...
The development of ICT (Information and Communication Technology) industry has emerged as one of the major sources of world energy consumption Especially, energy consumption on base station is a large portion of total energy consumption In this paper we study with energy efficient power control mechanism for base station in mobile communication systems. We proposed a efficient sector power control...
The wireless sensor networks is a network technique for the implementation of Ubiquitous computing environment. The nodes use the CSMA/CA for the communication. However, the number of nodes which are joined from the PAN coordinator is more increasing, also the competition and the overhead are more increasing. Therefore, the performance of current standard is decrease. In this paper, we design an efficient...
Wireless Sensor Networks (WSN), consisting of a large number of sensor nodes connected through wireless medium has emerged as a ground-breaking technology that offers the unprecedented ability to monitor the physical world accurately. Because of resource-constrained nature of sensor nodes, a number of issues have emerged out of which energy-efficiency is an important matter of concern. In this work,...
