The Internet is becoming increasingly mobile. Although several mobility solutions are proposed, none of them has been largely deployed. We propose a new system that can facilitate and support mobility on the Internet. The new mobility support service will be offered as a value-added service by mobility service providers to paying mobile customers. Therefore, the proposed solution is economically viable...
Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. In this paper, we investigate packet loss, routing loss and transport loss in mobile Wireless Sensor Networks (WSNs) considering AODV protocol and different radio models. We compare the simulation results...
In this work, we carry out a comparison evaluation for mobile and static sensor nodes in Wireless Sensor Networks (WSNs) using TwoRayGround propagation model and different protocols. We consider packet-loss and delay metrics to evaluate the performance of WSN. The simulation results have shown that for WSN with mobile sensor nodes, the delay is better than static sensor nodes. In case of static sensor...
In this paper, we implement a simulation system for single and multi-mobile sinks in wireless sensor networks considering TwoRayGround and Shadowing propagation models, using DSR routing protocol. We investigate how the sensor network performs in these cases. We used the good put and consumed energy metrics for performance evaluation. From simulations, we have shown that the good put of multimobile...

Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. However, the decision for CAC is very challenging issue due to user mobility, limited radio spectrum, and multimedia traffic characteristics. In our previous work, we implemented a fuzzy based CAC system called FACS-MP, which consider many priorities. In this paper,...
Event detection is a major issue for applications of wireless sensor networks. In order to detect an event, a sensor network has to identify which application-specific incident has occurred based on the raw data gathered by individual sensor nodes. Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment...
In this paper, we evaluate the performance of WSNs for single and multi mobile events using Two Ray Ground radio model and AODV protocol. We consider good put and routing efficiency metrics to evalute the performance of WSN. The simulation results have shown that for single mobile event, the good put is better than multi mobile events when the number of sensor nodes is higher. In case of boids model,...
The support for mobility is a major requirement for the next Internet. Although several mobility solutions are proposed, none of them has been largely deployed, due to various impediments, among which, non being economically viable, we believe is the principal one. We propose a business oriented mobility framework - Mobility Support Service (MSS), that will facilitate mobility on the Internet. MSS...

We investigate how the sensor network performs...
Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure.

Wireless Sensor Networks (WSN) are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro sensors to larger scale, controllable weather-sensing platforms. In this work, we investigate how the sensor network performs in the...
The importance of mobility in networks is being increased together with its number of users and applications. However, we still do not have broadly accepted solutions for mobility in Internet or other type of networks. In particular, mobility is difficult in heterogeneous networks, where heterogeneity could expand over ownership, administration, technology, and so on. We propose for such heterogeneous...
The mobile cellular systems are expected to support multiple services with guaranteed Quality of Service(QoS). But, the ability of wireless systems to accommodate expected growth of traffic load and broadband services is limited by available radio frequency spectrum. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning...
