Mobile Ad-hoc NETworks (MANETs) consist of mobile devices that rely on wireless media for bilateral communication. These can be set up anywhere and at any time because these require neither infrastructure nor central administration. This paper concentrates on the comparative performance evaluation of three reactive routing protocols Ad Hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA) for the three different Physical Characteristics namely Direct Sequence, Frequency Hopping and Infra Red in campus network of Guru Nanak Dev University, Amritsar using OPNET MODELER version 14.5. The performance metrics used for the authors' simulation are Wireless LAN delay, Retransmission Attempts, Throughput and Media Access Delay.
