We propose a multi-objective Pareto-optimal technique using Genetic Algorithm (GA) for group communication, which determines a min-cost multicast tree satisfying end-to-end delay, jitter, packet loss rate and blocking probability constraints. The model incorporates a fuzzy-based selection technique for initialization of Quality of Service (QoS) parameter(More)
The increasing demand of real-time multimedia applications in wireless environment requires stringent Quality of Service (QoS) provisioning to the Mobile Hosts (MI. The scenario becomes more complex during group communication from single source to multiple destinations. Fulfilling users demand with respect to delay, jitter, available bandwidth, packet loss(More)
In the development of wireless sensor networks (WSNs) applications, organizing sensor nodes into a communication network and route the sensed data from sensor nodes to a remote sink is a challenging task. Energy efficient and reliable routing of data from the source to destination with minimal power consumption remains as a core research problem. So, in WSN(More)
The energy problem in wireless sensor networks (WSN) remains one of the major barriers preventing the complete exploitation of this technology. Sensor nodes are typically powered by batteries remains a limited resource to be consumed judiciously. Efficient energy management is thus a key requirement for optimal utilization of the sensor network technology.(More)
Collection of information from critical situations where human beings find difficult to exist is a challenging task. In such scenarios tiny micro-sensors are densely deployed for monitoring the target objects or observing certain events to occur. The sensor nodes collect information from the target nodes, communicate with their neighbors and then forward(More)
A synchronized network time is always necessary for scheduling to achieve energy efficiency, data fusion, localization for WSN applications. The major limitation in a WSN is the battery usage and lifetime of the nodes. Due to the power restriction of nodes, efficient routing is very important to save the battery of sensors to enhance the lifetime of the(More)
The unpredictable movement of mobile nodes consequences dynamic change of topology as well as breaking and reestablishment of links among of the network nodes. The failure of links, not only change the network size but creates an environment for the intruders to become members of the network, which is a major security concern. Detection of such unwanted(More)
Evaluation of certain properties of calcined alumina or special grade alumina is necessary and important to its manufactures. Generally it is determined in the laboratories using different instrumental and manual methods, which is cost and time intensive. In the present work, evolving neural network has been used for the estimation of a property given few(More)
Wireless sensor nodes are mostly battery operated, tiny in size, and deployed in some specified area. The limited capacity of the battery power hinders the performance of the node as well as of the network. This requires efficient management of battery power for optimal utilization of the sensor network technology. In this work we propose a novel method to(More)
The exponential increase of multimedia services by the mobile users requires seamless connectivity with costeffective Quality of Service (QoS) provisioning. For providing such on-demand QoS, the network needs to utilize the radio channels among the Mobile Hosts (MHs) effectively. We use vector genetic algorithm (VGA) for temporal imploration of sharable(More)
