Tremendous efforts have been conferred towards the congestion control concern in mobile wireless networks while dealing with maximizing both throughput and fair bandwidth allocation. Unfortunately, this is made limited by the variable and unpredictable behaviour of such networks. In this paper we propose a new congestion control mechanism for multimedia traffic in mobile wireless networks. Our proposed...
Wireless sensor networks (WSNs) are highly susceptible to jamming attacks due to their resource limitations. In WSN architecture, the Base Station (BS) is a single point of failure, because it collects sensor readings and performs command and control tasks. So BSs are main targets of the jamming attack. For mitigating the effects of BS jamming attacks, we propose a hybrid model of defense, which combines...
Delay tolerant network (DTN) based on vehicular communications (i.e., vehicular delay tolerant network or VDTN) is considered in this paper. In VDTN, there is no direct end- to-end connection between the source and destination (i.e., sink). The traffic source transmits data to a mobile router. This mobile router in a vehicle receives and stores data in a buffer. The vehicle can move and once it is...
