A Wireless Sensor Network (WSN) plays a very important role within the future wireless communication domain due to its intelligence, low cost and small size. With the wireless interfaces, these will communicate with one another just in case of cooperative communication in single or multiple hops. Multiple nodes are required for co-operative communication where the Stable Enable Protocol (SEP) and...
With the ability to work under critical environments where human interception is difficult, wireless sensor networks serves as a useful communication means for data transmission and collection. But like other wireless networks WSN is also prone to adversary interventions. So the researchers are addressing this issue to make routing protocols secure for communication. But due to the severe resource...
Wireless sensor networks consist of nodes among which beaconing of data occurs through routing. There are a number of routing protocols and algorithms existing based on different criteria. There are a number of shortest path algorithms available, some of which are applicable in case of shortest path routing in wireless sensor networks. Shortest path routing algorithms aim at consumption of minimum...
In this paper compared the algorithms proposed in the method in wireless sensor network. Energy consumption is very important for self-powered radio nodes. But in some applications energy balancing is more important. Wireless sensor networks used in large areas like farmland or warehouses consist of hundreds of nodes. In classic method routing is directed to short time of transmission or low energy...
Wireless Sensor Networks (WSNs) are composed of many sensors which are densely or sparsely deployed to get the necessary information. They are constraint on resources such as energy, memory, computational speed and communications bandwidth. Particularly power is another major issue in WSNs, therefore main stress has been given to minimize the number of transmission to extend sensor service time in...
This work focuses on developing cool store's thermal mapping system based on the neuro Wireless Sensor Network (nWSN). The network intelligence is taken care of by the sensor network embedded neural net. The target application of the architecture development is for cool stores with emphasis on meat storage. The meat quality is a significant characteristic within the cold chain management. Temperature...
Energy constraint is an important issue in wireless sensor networks. This paper proposes a distributed energy optimization method for target tracking applications. Sensor nodes are clustered by maximum entropy clustering. Then, the sensing field is divided for parallel sensor deployment optimization. For each cluster, the coverage and energy metrics are calculated by grid exclusion algorithm and Dijkstra's...
In wireless sensor network, a lot of sensory traffic with redundancy is produced due to massive node density and their diverse placement. This causes the decline of scarce network resources such as bandwidth and energy, thus decreasing the lifetime of sensor network. Recently, mobile agent is proposed as a solution to overcome these problems. Mobile agent accounts for performing data processing and...
Detection of certain events or targets constitutes an important application of wireless sensor networks (WSN) in which spatially distributed nodes communicate to a decision center. Compared with such decision-centric communication strategies extensively proposed in literature, however, data-centric distributed detection scheme is rather a new design methodology. In this paper, we simulate and determine...
