The key issue of designing protocols for Wireless Sensor Networks (WSN) is Energy efficiency what needs to be enhanced to improve the entire network's lifetime. In this paper, we proposed EELLER that stands for Energy Efficient-Low Latency Express Routing. It is a hierarchical routing protocol based on clustering to minimize the number of hops required for data reporting as well as achieving energy...
Design an energy efficient routing protocol for wireless sensor network is a very important issue because of the constrained energy of sensor nodes. In this paper, an energy efficient routing protocol (VBT-EBHRP) is proposed. In this protocol, a virtual backbone tree is constructed and based on the virtual backbone tree, a routing tree is constructed. The residual energies of the virtual backbone...
In wireless sensor network, we have 2 type of routing; one of them send data from the sensor nodes to the sink and another send some data from sink to the sensor nodes such as programming/retaking binaries, queries and commands. In this paper we present a new routing algorithm base on ID that is named ID-Leach. This protocol assigns an unique ID with binary number to each sensor nodes. This protocol...
A wireless sensor network (WSN) is composed of a large number of sensor nodes which are resource constraints, e.g., limited power. This drives research on how to design routing protocols to gather data efficiently so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multi-hop. However, it gives rise...
For wireless sensor networks (WSNs), how to design routing protocols is very important to gather data efficiently so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multi-hop. However, it gives rise to two problems. The first one is the hotspot problem, in which the sensor nodes closer to the sink...
In wireless sensor networks, the simplified and energy efficient protocol should be designed in order to maximize the network lifetime because of its stringent resource constraints, ultra power limitation, and tiny embedded devices. In this paper, we propose an enhanced cross-layer protocol for energy efficiency in wireless sensor networks by integrating medium access control and routing protocol...
Wireless Sensor Networks (WSNs) have inherent and unique characteristics. One of the most important issues is their energy constraint. Energy aware routing protocol is very important in WSN, but routing protocol which only considers energy has not efficient performance. Congestion management can affect routing protocol performance. Congestion occurrence in network nodes leads to increasing packet...
MELEACH-L proposed in this paper as an expanded version of MELEACH makes the major functions of MELEACH applicable to large-scale WSNs whose dimension is much larger than the largest transmission radius of the sensor nodes. The channel assignment among neighbor clusters and the cooperation among cluster heads during data collection are two major difficulties in a large WSN. MELEACH-L solves the two...
Body sensor networks are an interesting emerging application of wireless sensor networks to improve healthcare and the quality of life. Current research has mainly focused on single-hop networks, although some works clearly show advantages of multi-hop architectures. In this paper, we model probabilistic connectivity in such multi-hop body sensor networks. Instead of using a circular coverage area,...
In wireless sensor networks (WSNs), a challenging problem is how to advance network QoS. Energy-efficiency, network communication traffic and failure-tolerance, these important factors of QoS are closely related with the applied performance of WSNs. Hence a QoS-aware routing protocol called directed alternative spanning tree (DAST) is proposed to balance the above three factors of QoS. A directed...
