Geographic routing protocols are one of the most common routing schemes for sensor networks. These protocols consist of two different modes of operation: greedy routing to forward data to the destination using neighbors which are closer to the destination than current node and face routing to avoid voids in the network. Face routing requires the graph to be planar, which usually means that some...

In this paper, we propose VANET Cross Link Corrected Routing (VCLCR), a simple yet novel, event-driven geographic routing protocol that removes cross links dynamically to avoid routing loops in urban Vehicular Ad Hoc Networks (VANETs). VCLCR uses the natural planar feature of urban maps without the problematic planarization strategy. The salient features of dynamic loop detection and statelessn...

In the near future extremely large scale mobile adhoc networks of thousands or tens of thousands of mobile nodes will be physically feasible and desirable for a host of applications. However, routing within these networks is challenging, especially at high data rates and when node movement is highly-dynamic. In this work we present Topology Aware Geographic Routing (TAG), a position-based routi...

In this paper, we propose an efficient geo-routing aware MAC protocol (GOAL) for underwater acoustic networks. It smoothly integrates self-adaptation based RTS/CTS, geographic cyber carrier sense and implicit ACK to do combined channel reservation and next hop selection. As a result, it possesses the advantages of both geo-routing protocol and reservation based MAC protocol. Specifically, its s...

The development of routing protocols for mobile ad hoc networks is a challenging and active research area, and a variety of approaches have been developed. Among them, geographic routing strategies use knowledge of the devices’ physical positions to achieve efficient routing performance – a critical goal for networks of resource-constrained devices. Strategies have also been developed to perfor...

Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery.

Abstract — Wireless sensor networks have attracted great attention in research and industrial development due to its fast-growing application potentials. New techniques must be developed for sensor networks due to their lack of infrastructure support and the constraints on computation capability, memory space, communication bandwidth, and above all, energy supply. To prolong the life time of a ...

In this paper, we address Quality-of-Service (QoS)-aware routing issue for Body Sensor Networks (BSNs) in delay and reliability domains. We propose a data-centric multiobjective QoS-Aware routing protocol, called DMQoS, which facilitates the system to achieve customized QoS services for each traffic category differentiated according to the generated data types. It uses modular design architectu...

Geographic protocols are very promising for wireless ad hoc and sensor networks due to the low state storage and low message overhead. Under certain idealized conditions, geographic routing – using a combination of greedy forwarding and face routing – has been shown to work correctly and efficiently. In this work we model and analyze the correctness of geographic routing under non-ideal realist...
