The sensors in sensor networks have limited energy and thus energy preserving techniques are important but in many cases like war zone the time for complete a task is more important than energy and in large-scale sensor networks, redundant communication between sensor nodes is necessary to propagate data in a large monitoring region. The main objective of this paper is to efficiently disseminate information...
Wireless sensor networks (WSN) have been considered as a promising method for reliably monitoring both civil and military environments under hazardous or dangerous conditions. Due to such environments, the power supplies for sensors in the network are not usually rechargeable or replaceable. Therefore, the energy efficiency is critical for the lifetime and cost of WSN. Numerous mechanisms have been...
PEGASIS, a chain-based protocol, forms chains from sensor nodes so that each node transmits and receives from a neighbor. In this way, only one node (known as a HEAD) is selected from that chain to transmit to the sink. Although PEGASIS is able to balance the workload among all of the nodes by selecting the HEAD node in turn, a considerable amount of energy may be wasted when nodes which are far away...
Power consumption is the main challenges of expanding the network, since the active nodes are more vulnerable to energy consumption. This paper proposes the tasks scheduling and distribution energy management mechanism of roles dormant cells (SRDC) to curb excessive consumption of energy consumed in the performance of duplicates task and unhelpful. Experimental results verify that the proposed of...
