In this paper we propose a routing protocol for wireless ad hoc networks whose nodes are largely battery powered. The battery capacity of the nodes is viewed as a common resource of the system and its use is to be optimized. Results from a previous study on battery management have shown that: (1) pulsed current discharge outperforms constant current discharge, (2) battery capacity can be improv...

Wireless sensor network (WSN) consisting of a large number of sensor nodes is effective for gathering data in a variety of environments. Since the sensors operate on battery of limited power, it is a challenging task to design an efficient routing scheme which can minimize the delay while offering high energy efficiency and long network lifetime. Achieving both energy efficiency and scalability...

In MANETs, there are many routing protocols like table-driven and on-demand routing protocols. Among these protocols, on-demand routing protocols are very sensitive in achieving the major challenges of MANET such as routing, security, bandwidth, quality of service and reliability and so on. The most popular on-demand routing protocols are Ad-hoc On-demand Distance Vector (AODV), Dynamic Source ...

Position aided routing protocols can offer a significant performance increase over traditional ad hoc routing protocols. These routing protocols use geographical information to make forwarding decisions, resulting in a significant reduction in the number of routing messages. However, current position aided routing protocols were not designed for use in high-risk environments, as position inform...

Hierarchical-based protocols are some of the most popular routing schemes used in wireless sensor networks due to their favorable, energy-saving properties. However, when it comes to large-scale wireless sensor network applications, these algorithms suffer from an increase in computational complexity and latency. In this paper, a parallel algorithm for the hierarchical-based protocol has been d...

In today's world the security vulnerabilities are increasing day by day. It is really difficult to route the packet with minimum packet loss with less power consumption and high energy efficiency. In this paper a new routing protocol is presented which would route the packets in a highly efficient way by introducing the concept of friend list, unauthenticated list and question mark list. T...

Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

Energy conservation is an essential and critical requirement for a wireless sensor network with battery operated nodes intended for long term operations. Prior work has described different approaches to routing protocol designs that achieve energy efficiency in a wireless sensor network. Several of these works involve variations of mote-to-mote routing (flat routing) while some make use of lead...

In this paper, we investigate the benefit of network coding over routing for multiple independent unicast transmissions. We compare the maximum achievable throughput with network coding and that with routing only. We show that the result depends crucially on the network model. In directed networks, or in undirected networks with integral routing requirement, network coding may outperform routin...

Routing efficiency is one of the challenges offered by Mobile Ad-hoc Networks (MANETs). This paper proposes a novel routing technique called Adaptive Link-Weight (ALW) routing protocol. ALW adaptively selects an optimum route on the basis of available bandwidth, low delay and long route lifetime. The technique adapts a cross-layer framework where the ALW is integrated with application and physi...
