Several localization techniques have been proposed to identify the exact location of sensor nodes. Localization is important for computation of many applications such as routing in wireless sensor network. Energy preservation is a challenge in wireless sensor network and many algorithms have already been proposed. The localized node lifetime is maximized by using energy-efficient routing, use of minimum...
The end-to-end packet delay in mobile ad hoc network depends on many influential variables such as path length from source to destination, average number of neighbours of intermediate hops, interference from other transmissions and medium access control protocol etc. Hence, accurate prediction of end-to-end packet delay is very difficult but necessary for Quality of Service (QoS) routing in Mobile...
In high-mobility cognitive radio networks (CRNs), the fast topology changes increase the complexity of the routing scheme. In this paper, we propose a novel CRN routing scheme that considers the path stability and node capacity. First, a realistic mobility model is proposed to describe the movement of highly mobile airborne nodes [e.g., unmanned aerial vehicles (UAVs)] and estimate the link stability...
In this paper, we analysis and simulate the AODV and OLSR routing protocols for both Wireless Ad-hoc Network and Wireless Mesh Network. An Ad-hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Wireless Mesh Networks (WMNs) have recently gained a lot of popularity due to their...
