The main cause of the wasted energy consumption in wireless sensor networks is the packet collision. The packet scheduling algorithm is therefore introduced to solve this problem. This paper presents an analytical model for predicting the performance of packet scheduling algorithms in wireless sensor networks. This model can be used to predict the performance of the packet scheduling algorithm ...

Mobile Ad Hoc Networks are the set of mobile hosts operating without the aid of the established infrastructure of centralized administration. Due to lack of infrastructure, the network can be easily affected by several attacks. In addition to node mobility, a MANET is characterized by limited resources such as bandwidth, battery power, and storage space. The underlying assumption in MANETs is t...

VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...

Vehicular Ad-hoc Network (VANET) represents a challenging class of mobile ad-hoc networks that enables vehicles to intelligently communicate with each other and with roadside infrastructure. VANET poses number of challenges in terms of Quality of Service (QoS) and its performance. Quality of Service depends on numerous parameters such as bandwidth, packet delivery ratio, data latency, delay var...

We analyze the packet delivery performance of wireless cooperative relaying in an interference limited scenario, by means of stochastic geometry. We show that the temporal and spatial characteristics of interference play a significant role in shaping the system performance. In particular, when interference has high temporal and spatial dependence, the packet delivery probability increases for h...
