Visible Light Ad Hoc Networks (LANETs) have the potential to offer capabilities to satisfy growing industrial and military requirements, including low-latency, high bandwidth communication under high network density and jamming conditions. The challenges imposed by hidden nodes, deafness and blockage are unique to LANET and influence the network differently from traditional Mobile Ad Hoc Networks (MANETs) due to directionality and Line of Sight (LOS) requirements. Therefore, networking protocols have to be redesigned with careful consideration of these challenges. As an initial step in this direction, this paper proposes a utility based opportunistic three-way handshake mechanism to negotiate medium access. First, a node chooses the optimal transmission sector, i.e., the ”direction” that maximizes the probability of establishing a link even when some of the neighbors are affected by blockage or deafness …
