Modeling routing overhead generated by wireless reactive routing protocols

Abstract

In this paper, we have modeled the routing overhead generated by three reactive routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and DYnamic MANET On-deman (DYMO). Routing performed by reactive protocols consists of two phases; route discovery and route maintenance. Total cost paid by a protocol for efficient routing is sum of the cost paid in the form of energy consumed and time spent. These protocols majorly focus on the optimization performed by expanding ring search algorithm to control the flooding generated by the mechanism of blind flooding. So, we have modeled the energy consumed and time spent per packet both for route discovery and route maintenance. The proposed framework is evaluated in NS-2 to compare performance of the chosen routing protocols.

Ant colony optimization based enhanced dynamic source routing algorithm for mobile Ad-hoc network

“…E-Ant-DSR algorithm shows significantly lower routing overhead than all these algorithms in both sparse and dense network. Also, the routing overhead indirectly measures the energy consumption of the routing protocols [29] which indicates that our scheme consume lesser energy than other schemes. To further find the efficiency of our scheme in energy consumption, we compare the energy consumption of these schemes in the simulation environment.…”

“…So, from the energy analysis of Eqs. (10)- (29), the required energy of a node can be pre-determined.…”

“…When a sender needs to send a data packet, it sends the Req.Ant packets to all the links stored in RSSM cache. So the number of Req.Ant packet broadcasted by the sender node is equal to the number of neighbor it has within 0.9054R, where R is the range of the node antenna.The average number of connected neighbor node can be given as [29],…”

Investigating quality routing link metrics in Wireless Multi-hop Networks

“…In [15], we have modeled the routing overhead generated by three reactive routing protocols; AODV, DSR and DYMO. We have modeled the energy consumed and time spent per packet both for route discovery and route mainte-nance.…”

“…The works in [9][10][11][12][13], study the most widely experimented and frequently used protocols for our study; three from reactive or on-demand class: AODV, DSR, DYMO, and three from proactive or table-driven class DSDV, FSR, OLSR. .…”
