Wireless Sensor Network (WSN) is a large network of sensor nodes, which operates in low power and capable of transmitting to a shorter distance with low bandwidth. It comprises of sensing unit, processing unit, memory unit, power supply and transceiver. As these sensor nodes are battery operated, the lifetime of the sensor node depends on the life of the battery. The sensor nodes in the network communicate...
Wireless Multimedia Sensor Network (WMSN), as a novel technology, has attracted more and more attention with its board applications nowadays. The paper discusses the major challenges in current WMSN and focusing on some protocols relatively better fitting in the requirement of WMSN. Then a novel routing protocol CBRP-L basing on Cluster-Based Real-time Routing Protocol (CBRP) is proposed in this paper,...
To support high scalability and better data aggregation, sensor nodes are often grouped in to disjoint and mostly non overlapping sub sets called clusters. Clusters create hierarchical WSNs which facilitate efficient utilization of limited resources of sensor nodes and thus extends network lifetime. ZigBee, a communication standard for LR-WPAN (Low Rate Personal Area Networks), has low power consumption,...
In WSNs' application, the reduction of energy consumption and the entire network's lifetime should be optimized and feasible communications are must be ensured. All of the above have become to be an important factor to evaluate the performance of routing protocols. In the paper, we present a feasible routing protocol for WSNs in coal mine. Here, we call it LEACH-mine. In the algorithm, the cluster...
In WSNs, energy efficiency of the network is considered with utmost priority in order to lengthen the lifespan of the network. This paper proposes a two layer hierarchical routing protocol called Chain Routing Protocol based on Coordinate Clustering Strategy (CRBCC), which ensures the minimum energy consumption and short delay. At first, CRBCC makes cluster equally according to y coordinates. Then,...
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...
In the last few years, wireless sensor networks have gained a lot of interest in the research field. WSNs consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing protocols have been proposed for WSNs. Most of the hierarchical algorithms proposed for WSNs concentrate mainly on maximizing the lifetime of the network by trying to minimize the energy consumption,...
