Cogeco Data Services (CDS) was founded in 2000 as Toronto Hydro Telecom, a utility telecom that offered network services and colocation services. In 2008 the company was acquired by Cogeco Cable, a Montreal-based communications company with assets in telecom, radio, television and media. CDS’s presence stretches from the eastern reaches of Quebec to Windsor, Ontario.

Wireless Ad hoc network is a set of wireless devices which move randomly and communicate with other node via radio signal. Ad-hoc networks may be logically represented as a set of clusters by grouping together nodes on the basis of different criteria such as 1-hop and k-hop that are in close boundary with one another. Clusters are formed by diffusing node identities along the wireless links. Different heuristics employ different policies to elect cluster heads. Several of these policies are biased in favour of some nodes. As a result, these nodes should greater responsibility and may deplete their energy faster, causing them to drop out of the network. Therefore, there is a need for load-balancing among cluster-heads to allow all nodes the opportunity to serve as a cluster-head. In this paper, different cluster head election mechanism are discussed in the one hop clustering approach.
This paper clearly explains about the safety and control systems in the car . Most of the accidents are occurred because of violation of rules . Result of this major accidents happened .In our day-to-day life we are careless in our safety while driving in vehicles for this we have to introduce some techniques to do these precautions compulsory . Such a new technique is explained in this paper.While driving car wearing seat belt is important that can safe our life during accident periods .But most of us are careless to wear seatbelt .
Wireless ad-hoc sensor networks and routing data in them is a significant research area. The objective of this paper is to examine resource depletion attacks at the routing protocol layer, which attempts to permanently disable network nodes by quickly draining their battery power. This type of attack is called as vampire attack. Vampire attacks are very difficult to detect because they attack the node only by sending protocol-compliant messages.
A field study was conducted at the Teaching and Research Farm, University of Agriculture, Makurdi, Nigeria in 2008 and 2009 cropping seasons. The objectives were to identify important determiners of yield characters and to determine the correlations between growth characters viz: number of leaves per plant, length of internodes per plant, number of internodes per plant, leaf area index, net assimilation rate, absolute growth rate, plant height; and yield characters namely: panicles per plant, capsules per plant, capsules per panicle, seeds per plant, dry weight of harvestable material, total dry weight per plant, harvest index, seed yield, 100 seed weight and oil yield at 4, 8, 12, 16, 20, 24 and 28 weeks after sowing(WAS).
Network Security is always foremost and big issue in wired and wireless network. Wireless network, whether it is infrastructure mode or mobile adhoc mode, breaks the barriers of wired network and are easily accessible to everyone but everything is at a cost, the cost is in the form of increased susceptibilities and vulnerabilities of network. Packet delay is a result of poor utilization of network capacity when it is integrated with routing algorithms. Routing protocol contains very serious security issues in adhoc network. The code of AODV and DSDV are having such issues and new protocol are extended in the form of SEAD, SEAR and SAODV. This paper analyses the ways the security is breached by the hackers who emerge as malicious node in Infrastructure as well as in adhoc mode of network. The handiwork is prepared by way of Developing experimental Testbed and simulation in NS2 then proper measure are proposed in order to overcome all the problems.

Bad news always makes the headlines, while good news is rarely reported and, over the past 15 years we’ve seen constant negative headlines when it comes to stock markets. We’ve witnessed two huge market crashes, with the end of the tech bubble in 1999 and the recent financial crisis of 2008 resulting in almost 50% declines. Then every few months we hear of another company blowing up. The latest examples are Tesco, Balfour Beatty and Quindell, and there have also been the Madoff and Enron fraud scandals!
