A new scheme that serves to find a routing path for Wireless Sensor Networks (WSNs), with a view to facilitate an increase in the network life time is proposed in this paper. It envisages the network to be in the form of clusters and develops an algorithm for transfer of information within the nodes and to the remote Base Station (BS). The approach involves the use of Ad-hoc On Demand Distance Vector...
The following topics are dealt with: distributed simulation; real-time application; large scale simulation; virtual reality; performance; mobile network; and sensor network.
The following topics are dealt with: mobile network; I/V communication; features scene categorization; texture classification; image classification; video surveillance sequences; wireless sensor network and protocol; face recognition; cryptography and watermarking; video coding; content based indexing and retrieval; signal and speech processing; and biomedical image processing.
On the background of integration of WSN and mobile network, the mobile agent nodes access to mobile network through the base station and sent data to the remote server to deal with. Because the resource is limit for the mobile network, the throughout of the mobile agent node has threshold. We propose an algorithm for rate control based on non-cooperative Game Theory, which will assign different rate...
This paper presents CARNIVORE, a system for in-situ, yet unobtrusive monitoring of cryptic, difficult-to-catch/observe wildlife in their natural habitat. CARNIVORE consists of a network of mobile and static nodes that have sensing, processing, storage, and wireless communication capabilities. One of CARNIVORE'S notable novel features is its robustness to intermittent node connectivity since, depending...
The wireless ubiquitous network and various communication services are expected to be realized. The wireless ubiquitous network is defined as the converged network to integrate the mobile network with the fixed IP based network. First, the concept of wireless ubiquitous network architecture is shown which is based on IMS standardized by 3GPP. Next, Parlay is described as the solution of Open API approach...
In order to solve the problem that program-code of the sensor node in wireless sensor network was difficult to upgrade, the application layer protocol OTA-WSN was presented. With reference to the OTA Technology applied in mobile network, this paper defined the functions of each communication sector in the protocol, including package's format of the application layer packages and data transfer protocol...

In this paper, we propose a passive solution which is low- cost, facilitates high adaptation rates and utilizes the non-IV vehicles to assist in ITS applications. RFID technology, a prominent identification technology, has the potential to turn everyday objects into a mobile network of nodes, which can then be used to track and trigger events. This briefly outline stand-alone and co-operative systems...
WCDMA radio access networks are dimensioned using traffic models containing traffic characteristics for a number of services offered by the operators and their networks today. Recent trends have seen a new class of traffic emerging, driven by wireless sensor network applications and machine-to-machine communication. This communication between ldquothingsrdquo has traffic characteristics very different...
Indoor localization is an emerging subject in the field of wireless sensor networks (WSNs) and even more in wireless mesh networks (WMNs). Off the shelf solutions are still missing, even though the new IEEE 802.15.4a/ZigBee standard enhances the precision of ranging. This paper describes a hybrid localization approach combining time of arrival trilateration (TOA) as being proposed in the IEEE 802...
Wireless sensor networks (WSN) are expected to form an integral part of the foreseen ubiquity intelligent, future mobile network and are envisaged to play a key role in the vision of offering mobile, personalised services, in-home and out-doors, whenever and wherever needed. However, security and resilience across WSN, especially across insecure, heterogeneous and multi-administration domains like...

We describe a family of log n protocols for assigning symmetric keys to n processes in a network so that each process can use its assigned keys to communicate securely with every other process. The k-th protocol in our protocol family, where 1 les k les log n, assigns O(k2kradicn) symmetric keys to each process in the network. (Thus, our (log n)-th protocol assigns O(log2 n) symmetric keys to each...
In this paper we suggest a wireless embedded system for estimating the closeness and the interaction time between mobile and fixed units for personal safety applications. In particular, the system provides a technological support during emergency or critical situations - where personnel has to safety move in a critical dynamic scenario - by automatically delimiting a dangerous area previously characterised...
Spatial query processing is important to the emerging mobile network applications such as ad hoc networks and mobile sensor networks. The conventional caching techniques are ineffective in dealing with spatial queries in dynamic environments due to the following reasons: first, the cache contents are described based on queries instead of data locations, which lead to the inefficiency in describing...
