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)
INTRODUCTION Seasonal Hyper Acute Panuveitis (SHAPU) is a sight threatening condition often affecting children. Its management as yet is a challenge in ophthalmic practice. Most of the eyes even after treatment end up in pthisis bulbi. MATERIALS AND METHODS A retrospective hospital based analysis of 18 patients with SHAPU managed with vitrectomy at(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)
This paper reports on the tree structure, tree dimension relationships and woody biomass production and removal of a sub-tropical natural forest in the Mamlay watershed of the Sikkim Himalaya. The forest provides fuel, fodder and timber to four villages. Only 11 tree species were found growing in the tree stratum despite the high diversity in the stand (32(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)
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)
In the Mamlay watershed of south Sikkim, India, about 80% of the population depend on land for their livelihood. The agricultural land-use activity includes agroforestry, horticulture and animal husbandry besides growing crops in irrigated or unirrigated fields. Trees are maintained in the farms mainly for fodder and rarely for fuel purposes. Cropping(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)
Fuzzy Cost Based Power Aware QoS Routing (FCPAQR) protocol proposed to select an optimal path by considering multiple independent QoS metrics. Fuzzy inference rule which is used to calculate the QoS based fuzzy cost of each link to forward the data packets effectively and efficiently. Fuzzy cost is calculated based on various QoS Constraints. QoS(More)
