Existing reliable-oriented routing protocols computes link reliability based on the packet reception ratio and neglects impact of various parameters such as noise, shadowing, battery-lifespan, uncertainty and geographic locations. In this paper, we propose a Link Reliable Reactive Routing (LR3) protocol for WSNs to accomplish reliable and resilience to out-of-order transmission and path diversi...

Routing plays a very significant role in multi hop data dissemination in Vehicular Ad-Hoc Networks (VANETs). Wehave proposed a Position based Adaptive Routing (PAR) protocol which is scalable for different network densities in VANETs. This scheme uses Preferred Group Broadcasting (PGB) for route discovery. In this mode, after broadcasting the request for route discovery the source node starts l...

Routing in Mobile Ad Hoc Networks (MANETs) has always remained a challenging task due to its dynamic topology and lack of centralized control. Several routing protocols have been proposed over these years starting with the traditional topology based protocols to the geographic routing protocols. The research over these years shows that the geographic routing protocols like Greedy Perimeter Stat...

A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...

In traditional routing, the routing tables store shortest paths to all other destinations and have size linear in the size of the network, which is not scalable for resource constrained networks such as wireless sensor networks. In this paper we show that by storing selectively a much smaller set of routing paths in the routing tables one can get low-stretch, compact routing schemes. Our routin...

In this paper we address the challenge of delivering a video stream with low latency in MANET. The major challenges while streaming video over MANETs are latency, control overhead. Latency and control overhead can be reduced by using Enhanced Efficient Geographic Multicast Protocol (EEGMP). The EEGMP uses a virtual-zone-based structure to implement scalable and efficient group membership manage...

High mobility and intermittent connectivity of nodes are the main characteristics Vehicular Ad-Hoc Networks (VANETs). These two aspects cause problems in traditional IP networking. Named Data Networking (NDN) is presented as one most promising paradigms for future Internet. NDN a data-centric architecture. It relies on data names instead host’s location to make forwarding decisions. In NDN, any...

The paper proposes a new approach to greedy geographic routing for sensor networks with non-convex covering structure.

Today’s material is based on three papers, which describe related routing methods. All of these methods proceed by defining virtual coordinates for the nodes, which are approximations to real Euclidean coordinates but are not actually Euclidean coordinates. These virtual coordinates are defined by means of hop-count distances from certain “landmark” (or “beacon”, or “perimeter”) nodes. The node...
