Nowadays, the problem of using minimum number of time slots for data aggregation such that sensors can work without data collision for data transmissions has received a great deal of attention in Wireless Sensor Network (WRSN). It is worth mentioning that there exists many approaches that are tried to reduce the number of time slots for data aggregation in WSNs. However, most of previous works are...
Because of the limited energies of sensors, efficient data gathering in wireless sensor network has been received a great deal of attention recently. To prolong the network lifetime, in this paper, we study the problem of scheduling a mobile sink to some specific nodes, termed anchor nodes in this paper, for data collection and reducing the energy consumption of data transmission. While considering...
A wireless sensor network (WSN) is composed of power-limited devices with constraints of size and condition etc. Due to impossibility to recharge or to replace the batteries of sensors, power control becomes a challenging issue in a WSN. To prolong the network lifetime, clustering is one of viable approaches. Among the clustering approaches, static clustering avoids the energy consumption in periodical...
Wireless Sensor Network (WSN) is an energy consumed network. Since most of the energy is consumed for transmitting and receiving data, the energy saving mechanisms plays a vital role in WSNs. One important mechanism to reduce energy consumption in the network is data aggregation. In-network data aggregation removes redundancy as well as unnecessary data forwarding, and hence cuts on the energy used...
It is widely known that the process and performance of data aggregation in wireless sensor network is dependent on the effectiveness of clustering mechanism. However, existing research work towards clustering mechanism has been found to focus on selection on cluster-head majorly on the basis on energy. This is the prime reason for which the energy effectiveness has not completely been achieved in...
Battery durability is often the major constraint in low power wireless sensor networks. Hence in most low power scheduling methods, nodes switch between the active mode and sleep mode periodically. This paper proposes an energy efficient data transmission scheduling for each node in a multi-channel multi-hop, data aggregation network. The proposed method reduces the active energy by scheduling each...
To select fair and balanced cluster head for cross layer protocol in wireless sensor network, a novel scheme is proposed in this paper. Because LEACH-C and its most of the variants select cluster head by considering energy and distance as a crucial parameter, it can reduce energy consumption of nodes but fail to create balanced cluster. According to the requirement of fair CH selection, we consider...
