Mobility pattern of an adhoc network affects its connectivity. Random Waypoint Mobility Model is widely followed by Mobile Adhoc Networks (MANET) in real world scenario. This mobility model is popular because it represents random motion of nodes which can move in any direction at any moment at a random speed. In this paper, the connectivity of a MANET, following Random Waypoint Mobility Model has...
In this paper, a new simulation tool is described which is used to present a decentralized approach on Mobile Ad Hoc Networks. The simulation is developed in Matlab using a decentralizing algorithm. The paper includes a distributed algorithm for adaptive movement of nodes in a MANET (Mobile Ad hoc Network) to maintain the overall topology of the network. The proposed algorithm assumes the presence...
Connectivity of Mobile Ad-hoc Networks (MANET) is highly dependent on the mobility model it follows. From previous studies, it has been found that Random Waypoint Mobility Model (RWP) is widely used to simulate performance of the MANETs. This mobility model resembles the mobility of people using mobile phones in a given area. Connectivity is an important issue in a MANET following RWP model and hence...
We study the problem of computing an energy-efficient data delivery scheme in wireless sensor networks that leverages the knowledge of a set of trajectories of mobile sinks in the network to route data from the sensors to the mobile sinks. Sensors collect data from the environment and instead of directly sending them to the mobile sinks (henceforth simply “sinks”), they route data to a number of selected...
Security remains as a concern in MANET. In case of multicast MANET it is even more challenging as most of the routing protocols have been proposed assuming that the nodes in MANET behave in a secure manner. In this paper we are outlining a secure novel multicast routing protocol named Secure Hypercube Based Team Multicast Routing Protocol (S-HTMRP) that deals with both multicast routing and packet...
This paper proposes a new token-based mutual exclusion algorithm for directed graph topology, with or without cycles. In one of our earlier works, we have introduced a token based algorithm assuming an inverted tree topology. Such a stable, hierarchical topology is quite unrealistic for mobile networks due to frequent link failures and node mobility. The proposed solution overcomes this. Besides maintaining...
