Abstract :
Asymmetric/unequal radio links (ARL) in wireless communication can occur in MANETs/VANETs for many reasons such as hardware limitations, power saving protocols, shadowing effects, dynamic spectrum managements. Although largely overlooked, these ARLs are responsible for problems like hidden stations and exposed stations. This paper presents how Extended Sliding Frame Reservation Aloha (ESFRA) solves networking problems associated with ARLs. Performance of ESFRA has been compared to competing MAC protocols, namely IEEE 802.11 MAC and SFRA, proposed for VANETs. The simulation result shows that ESFRA provides about 80% channel utilization considering the effects of hidden stations due to ARLs.
