MANets are very sensitive to control overhead packets due to its limited capacity. If available bandwidth is not accurately estimated, nodes will accept extra QoS requests and network will be overloaded. To improve the available bandwidth and to reduce the control overhead associated with the backoff scheme employed in MAC (Medium Access Control) layer; pipelined concept is applied to backoff procedure. Pipelined process also reduces collision probability. When the medium is busy, remaining nodes start the contention procedure in parallel for the next packet transmission. This reduces the channel waiting time. Bandwidth loss due to collision, pipelined backoff and idle time synchronization are estimated and final available bandwidth is calculated. This bandwidth measurement algorithm is integrated into routing protocol called enhanced QoS AODV (Quality of Service Ad hoc On demand Distance Vector) to find the best route based on bandwidth constraint. Simulation results show that the proposed algorithm improves the performance of the network in terms of throughput, packet delivery ratio, effective bandwidth utilization, energy consumption for different number of nodes.

“…It uses hop count as criterion for choosing the route with an assumption that NODE_TRAVERSAL_TIME (NTT) is constant. Stephane Lohier et al [16] proposed reactive QoS routing protocol that also deals with delay and bandwidth requirements. In his proposal, QoS routes are traced by node to node and NTT is an estimate of the average one-hop traversal time, which includes queue, transmission, propagation, and other delays.…”

Distributed on-demand routing for LEO satellite systems

Notwithstanding the limited commercial success of the first narrowband Low Earth Orbit (LEO) satellite systems, the interest of the scientific community in this type of systems has been revived on the basis of the current trend toward the migration to all IP-based services. LEO systems can play a pivotal role in providing services to areas where there is no substantial terrestrial infrastructure. Above all, LEO satellite systems can be used as backbone networks to interconnect autonomous systems worldwide. Such an approach provides flexibility in managing the resulting integrated network infrastructure and supporting innovative applications. In this context, routing data from the source all the way to the destination constitutes a daunting challenge. In this paper, a location-assisted on-demand routing (LAOR) protocol is proposed and evaluated. The proposed protocol introduces for the first time in satellite systems the concept of on-demand routing. However, its implementation is tailored to the requirements imposed by the characteristics of the topology of LEO satellite systems. The performance of the LAOR protocol is assessed for different link-cost metrics and compared to the one of centralized routing protocols proposed in the literature so far. Simulation studies further document and confirm the positive characteristics of the proposed protocol.
