    A Comprehensive Review on Performance of AODV and DSDV Protocol Using Manhattan Grid Mobility Model
    (IJRET, 2014) Kaur, Amandeep; Mittal, Meenakshi
    Wireless networks have become an epitome of revolution in the communication industry as these have enabled the devices to communicate and access information independent of their location. These networks can be classified into two categories: Infrastructure based and Infrastructure less. Mobile ad hoc networks (MANET) fall under infrastructureless category in which nodes are able to move thereby making the topology of the network highly dynamic. Due to the dynamically changing topology, efficient routing mechanisms needed to be developed, which led to the foundations of various mobile ad hoc routing protocols. There are a number of mobile ad hoc routing protocols proposed to serve different purposes like security and transmission efficiency. These protocols are divided into two categories: Table based and Demand based. Through this work, table based traditional routing protocol DSDV and demand based routing protocol AODV have been assessed through simulation using Manhattan Grid mobility model. Comprehensive analysis was carried out to analyze which protocol performs better in the assumed scenarios. The performance metrics evaluated for the two protocols are Throughput, Average End to End delay, Routing Overhead and Packet Delivery Ratio

    Influence of link sensing mechanism of IMEP on the performance of TORA under different mobility models
    (Institute of Electrical and Electronics Engineers Inc., 2015) Kaur, Amandeep; Mittal, Meenakshi
    The performance evaluation of Mobile Ad Hoc Network (MANET) routing protocols is an important as well as open area of research worldwide. Temporally Ordered Routing Algorithm (TORA) is an adaptable and distributed MANET routing protocol which is dependent on the services of Internet MANET Encapsulation Protocol (IMEP) for its various necessary functions like link status detection. The incorrect link failure detection by IMEP leads to creation of congested network and initiation of avoidable route maintenance in TORA. Thus changes need to be introduced in the link sensing mechanism provided by IMEP to improve the detection of links in TORA. According to previously available research, if the maximum number of OBM retransmissions is increased, significant improvement in the performance of TORA is noticed. This modification has been implemented in this paper and performance of Enhanced TORA is evaluated under Random-Waypoint model, Manhattan-Grid mobility model and Random-Direction model using FTP traffic with 10 connections. The results are then compared with those of original TORA using various performance metrics like Packet Delivery Ratio, Average End to End Delay and Routing Overhead. ? 2014 IEEE.

    Analysis of MAODV MANET routing protocol on different mobility models
    (Institute of Electrical and Electronics Engineers Inc., 2018) Kaur, N.
    MANET is an infrastructure less network. It has various applications in fields like military, commercial sector, local level, etc. MANET is easy to setup, configure and build. Due to infrastructure less network, MANET relies on the cooperation of nodes for communication. In MANET, communication between the nodes is possible with the help of protocols which are categorized into three types like reactive, proactive and hybrid. In the reactive category of protocol, a path is established at the real time. In the proactive category, protocols have predefined routing tables for each node. The hybrid category is the combination of both these categories. Modified Ad-hoc On-Demand Distance Vector (MAODV) is the reactive protocol which defines all possible routes among source node and the destination node which are maintained during data transmission. In the case of a disappointment of definite route, the data packets are transferred through secondary routes which were established with the help of routing tables that stores the multiple route paths to the destination. In the real world, nodes in MANET are allowed to transfer in any direction. Thus movement models like Random Way Point (RWP), Random Walk (RW), Random Direction (RD) and Gauss-Markov (GM) are taken as they have different mobility patterns. Therefore, M-AODV is implemented over different mobility models to compute parameters like End to End Delay (E2E Delay), Average Hop Count (AHC), and Throughput. ? 2017 IEEE.
