We provide an analytical proof that the departure rate of a CBR flow at an overloaded link with FIFO buffers is proportional to the flow's share of the total offered load at the link. Exhaustive simulations have been done to analyze results, which are evaluated for performance metrics, such as throughput, packet delivery ratio and average end to end delay. The effect of variations in simulation time, number of nodes, and speed of mobile nodes on the network performance is analyzed over a wide range of their values. It is observed that the TCP/FTP offers a far better performance for throughput than UDP/CBR; in case of PDR, former offers an almost constant trend, whereas the latter shows highly varying (rising and falling) trends in all the three aforementioned scenarios. The average end to end delay of latter is lesser than former. The results follow these trends over a wide range of simulation parameters
