Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.
Routing in Wireless Sensor Networks has to take into account the limited battery resources of the nodes. Sensor nodes can also be powered by other energy sources like solar energy. This paper provides a review of Environment monitoring using Wireless Sensor Networks. The issues related to environment sensor networks is highlighted. The real time applications in environment monitoring is presented with emphasis on energy conservation. Furthermore in this paper we address the problem of scavenging energy using solar powered devices.
Mobile Ad hoc Network (MANETs) is an infrastructure – less network which is created by deploying the mobile nodes carrying wireless devices, able to route the data through multi hop fashion. MANETs uses distributed routing approach. In this paper, analysis of different classification of routing protocols such as: Reactive (AODV, DSR) Proactive (DSDV) and Hybrid protocols ZRP (Zone Routing Protocols) has been done using NS2 simulator. The above work analysis has been done on the following QoS parameters such as: Packet Delivery Ratio, Average Throughput, Routing Overhead and Average Delay

The study was made on morphometric parameters of human fetal kidney. The present study was carried out in the department of Anatomy, Government Medical College & Hospital, Chandigarh. The material for the study consisted of 30 spontaneously aborted human fetal specimens from 12 th to 28 th weeks of gestational ages. The kidneys were taken from fetal specimens for morphological study. The measurements were done compass, scale and vernier caliper. The present study established a significant and positive correlation between the length,breadth and thickness of kidney. All the parameters increased with increase in gestational age maximum increase was observed from group B-C.Correlation of kidney with suprarenal gland were positive. Length and thickness of kidney was more than suprarenal length and thickness, whereas breadth of kidney was less than breadth of suprarenal gland in all the age groups. All the parameters of kidney increased from that of suprarenal by approximately
Network coding has been recently applied to wireless networks to increase throughput. Back-pressure type algorithms based on the algorithmby Tassiulas and Ephremides have recently receivedmuch attention for jointly routing and scheduling over multi-hopwireless networks. we explore the performance of backpressure routing and scheduling for TCP flows over wireless networks. TCP and backpressure are not compatible due to a mismatch between the congestion control mechanism of TCP and the queue size based routing and scheduling of the backpressure framework. We decouple the routing and scheduling components of the algorithm by designing a probabilistic routing table that is used to route packets to per-destination queues. The scheduling decisions in the case of wireless networks are made using counters called shadow queues.

The mobile nodes in a network which can communicate with each other through a radio wave without any specific infrastructure is widely known as Mobile Ad-hoc Network(MANET). MANET has a number of routing protocols. The popular routing protocols so far are Dynamic Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), Ad-hoc On-demand Distance Vector (AODV) and Temporally-ordered Routing Algorithm (TORA) routing protocol. Among them the AODV routing protocol meets efficiently with the ad-hoc network specification.
