Wireless Sensor Network is made up of tiny nodes with ability to sense, communicate and compute due to the presence of battery, sensors, transceivers, memory, and processor in them. This paper deals with a single target tracking scenario performed with static as well as mobility optimized mobile sensor nodes in an energy conserving manner, hence the name hybrid sensor network. Using the static nodes...
A need for the benefits of high-speed internet access in the mobile environment has been increasing, with growing expectations for the implementation of Broadband Wireless Access (BWA) to exceed the transmission speeds of third generation mobile phone communications (3G). WiMAX extends the benefits of WiFi networks to deliver the next-generation mobile Internet. Integrating WiMAX and WiFi, it promises...
An ad hoc network comprises of mobile computing devices that use wireless transmission for communication. It has no fixed infrastructure. The mobile devices also serve as routers. Ad hoc wireless networks can be deployed quickly anywhere and anytime as they eliminate the complexity of infrastructure setup. It finds applications in military communications, emergency operations, hybrid wireless network...
Genetic Zone Routing Protocol (GZRP), a new multi path routing protocol for MANETs, is an extension of ZRP by using Genetic Algorithm (GA). GZRP uses GA on IERP and BRP parts of ZRP to provide a limited set of alternative routes to the destination in order to load-balance the network and robust when node/link failure occurs during the route discovery process. GZRP is studied for its performance and...
Present 3G Mobile Devices are often supports multiple communication technologies. If software developers want to control the configuration or monitor the characteristics of active Radio Access Technologies (RATs), their mobile applications will have to use different programming interfaces for each technology on various supported platform. We propose Modular Data Link Layer M-DALL for a NEXT GEN Mobile...
Service Providers (TSP) view Service Delivery Platform (SDP) deployment as an important step towards rapid application rollout (using an “Application Store” for example). It is expected that the new applications developed will exploit TSP's network capabilities along with their subscribers diverse device capabilities to deliver richer end user experience. This will create a value proposition for the...
Initially mobile phones were developed only for voice communication but now days the scenario has changed, voice communication is just one aspect of a mobile phone. There are other aspects which are major focus of interest. Two such major factors are web browser and GPS services. Both of these functionalities are already implemented but are only in the hands of manufacturers not in the hands of users...
An Ad-hoc network is a cooperative arrangement of the collection of mobile nodes without any centralized control. A central challenge in Ad-hoc networks is the design of routing protocols that can adapt its behavior with the frequent and rapid change in the network. The performance of the protocols varies with network characteristics and one protocol outperforms the other in some different network...
Notice of Violation of IEEE Publication Principles "CZM-DSR: A New Cluster/Zone-Disjoint Multi-Path Routing Algorithm For Mobile Ad-Hoc Networks," by S. Vijay, S.C.Sharma, V. Gupta, S. Kumar, in the IEEE International Advance Computing Conference, 2009, 6-7 March 2009 After careful and considered review of the content and authorship of this paper by a duly constituted expert committee, this...
With the increase in need for wireless appliances to support mobility, many schemes have been proposed to improve the quality of service (QoS) levels during handoffs. Although these schemes have been proven to be very effective in improving the latency and packet loss during handoffs to a significant level, they are mainly limited to micro-mobility scenario. In the context of macro-mobility, mobile...
