Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. An ad hoc network is a collection of wireless nodes dynamically forming a temporary network w...

The objective of this work is to compare with simulating, using OPNET the performance of five Ad hoc routing protocols: DSR, AODV, OLSR ,TORA and GRP , and to examine the impact of mobility and the density of nodes on the behavior of these protocols in a Vehicular Ad hoc NETwork (VANET). The results show that there is not a protocol that is favorite for all evaluation criteria. Indeed, each pro...

Real implementation of routing protocol of WSNs is a time consuming process and expensive due to simulation evaluation. This paper presents an organized performance study of three routing protocols, Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Optimized Link State Routing (OLSR) protocols for WSNs. The performance study of WSNs routing protocols is analysed by equa...

The main method for evaluating the performance of MANETs is simulation. This paper is subjected to the Dynamic Source Routing protocol (DSR) and evaluated its performance in three different placement environments namely Random, Grid and Uniform. We investigated the QOS metrics namely Average jitter, Average end-to-end delay, Packet delivery ratio and Throughput by varying network size. From the...

We present the Caching and Multi-Path (CHAMP) routing protocol, a new protocol for mobile ad hoc networks that uses data caching and shortest multiple path routing to achieve robustness against mobility and energy-efficiency. Simulation results show that a 5-packet FIFO data cache combined with 2 routes exhibits significantly better performance compared to DSR and AODV. At very high loads, CHAM...

In this work, we present the design of a mitigation scheme for jamming attacks integrated to the routing protocols MPH, AODV, and DSR. The resulting protocols are named MPH-M (Multi-Parent Hierarchical - Modified), AODV-M (Ad hoc On Demand Distance Vector - Modified), and DSR-M (Dynamic Source Routing - Modified). For the mitigation algorithm, if the detection algorithm running locally in each ...

Routing protocols are essential to the performance of wireless networks especially in mobile ad-hoc scenarios. The development of new routing protocols requires comparing them against well-known protocols in various simulation environments. In this paper, we present an overview of the well-known MANET routing protocols and the implementation details of the DSR routing protocol in the ns-3 netwo...

Summery Routing presents a significant design challenge to meet various applications requirements in wireless sensor networks (WSNs) communications. In this paper, we present a minimum delay multipath routing protocol with modification to the standard dynamic source routing (DSR) protocol, which aims to improve energy efficiency and minimize end-to-end delay to provide quality of service (QoS) ...

The Undersea Networking environment presents many challenges, such as limited network throughput and extreme latency. It is further hampered by the challenges faced with all Mobile Ad-Hoc Networks, with regard to rapidly changing network topology, AdHoc routing overhead, and dynamic network size. AUSNet (Autonomous Undersea Systems Network) is an NSF funded STTR Phase 2 program (with support fr...
