Abstract MANET is an autonomous wireless network without any centralized authority, consisting of a dynamic topology with multi-hop scenario. Clustering provides authority within and makes the stable up to some extent. Security one most challenging aspects, directly proportional load overhead over network. The model being proposed uses cluster-based technique modified secure routing protocol, w...

The performance of existing QoS routing protocols is often constrained with high control traffic and database maintenance overhead. We observe that by proper coupling of nodal mobility and location information, better QoS support can be achieved with reduced control traffic and database requirements. In this paper, we investigate the performance of a location-aware QoS routing protocol, called ...

Enhancing route request broadcasting protocols constitutes a substantial part of recent research in mobile ad-hoc network (MANET) routing. We suggest a novel approach to modify route request broadcast based on node caching. The intuition behind node caching is that the nodes involved in recent data packet forwarding have more reliable information about its neighbors and have better locations (e...

Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. The main classes of routing protocols are Proactive, Reactive and Hybrid. A Reactive (on-demand) r...

This document defines an optional extension to the REsource LOcation And Discovery (RELOAD) protocol to support the direct response routing mode. RELOAD recommends symmetric recursive routing for routing messages. The new optional extension provides a shorter route for responses, thereby reducing overhead on intermediate peers. This document also describes potential cases where this extension c...

Several strategies have been proposed for routing in the Low Earth Orbit (LEO) satellite networks. The multi-layered routing approaches are envisioned as promising because they use Middle Earth Orbit (MEO) satellite to extend the LEO satellite network’s communication capabilities. The previously proposed multi-layered routing approaches, however, still assume that the satellites in the same lay...

Instead of blindly searching for a route in the entire network, the location-based routing protocol uses the location information of mobile nodes to confine routing space into a smaller range that reduces routing overhead and broadcast storm. In this paper, we propose a location-aided cluster-based routing protocol called Core Location-Aided Cluster-based Routing protocol (CLACR). CLACR partiti...

In this paper, we employ gridded model for channel routing and place the terminals which are horizontally aligned. We have developed a two-layer channel router that can eliminate the constraints due to overlap. The proposed approach is suitable for cell/IP-based channel-less circuit with a few channels. Our developed tool can route the nets in nearly linear time achieving to the advantage of ti...
