When considering disaster scenarios, reliable communication can save hundreds of lives. Due to destroyed infrastructure, Mobile Ad hoc Networks (MANETs) might be the only option for communication in such scenarios. However, such MANETs get partitioned frequently due to node movements resulting in intermittent connectivity. Delay Tolerant Networks (DTNs) are suitable to handle this. With the help of...
In an ad - hoc network, major challenging work is to maintain fairness among multiple flows in heterogeneous applications. The proposed solutions in the available literature are mostly based on the first come first out (FIFO) queuing which dispatch packets according to the priority of the packet, based on its type of application or region of the source node. As a result, packets having lower priority...
In wireless ad-hoc networks where concurrent transmissions of data messages by hidden wireless nodes should be avoided, better trade off between reliability and transmission delay is required. The authors have proposed the method to adaptively apply either BEC (Backward Error Correction) or FEC (Forward Error Correction) based on bit error ratio and transmission request frequence. In FEC communication,...
Wireless sensor networks (WSNs) are becoming a viable tool for many monitoring applications. In many cases these applications may be of critical nature where the transmitting of vital information from sensors to base station or sink is crucial, and data loss cannot be tolerated. As a result, the information transmission of wireless sensor networks has various different requirements in performance,...
