“…STDMA [9,10] which is based on observing that no two contenders may reside at the same space coordinates at the same time, cannot be considered either since inaccuracies γ and τ need be assumed arbitrarily small for STDMA to be correct (or simply efficient). Ditto for SDMA [11] and LCA [12]. An additional unpleasant feature of existing V2V MAC protocols is the high variability of access delays, very small under modest traffic and contention, very large (close to unbounded) under high traffic and contention.…”

“…Many of these MAC protocols were designed for one-dimensional vehicular networks (e.g., [1], [4], [18], [23]); and only limited work exists on using geographical location to help define how nodes should share a common channel.…”

Abstract-Geographical Classification Multiple Access (GCMA) is introduced for scheduled channel access in large wireless networks. GCMA uses the geo-spatial coordinates of nodes, together with their transmission and interference ranges, to define collision-free transmission schedules using deterministic distributed algorithms. These algorithms require each node to know only the geo-spatial coordinates of its immediate neighbors to derive correct transmission schedules, even in the presence of hidden terminals. The transmission frames in GCMA consist of the minimum number of time slots needed to avoid multiple access interference, given the transmission and interference ranges of the nodes. GCMA is compared against representative examples of alternative approaches to medium access control; the results of the simulation experiments show that GCMA attains higher packet-delivery ratio and better goodput with end-to-end delay comparable to the other protocols.

“…The protocol we consider is based on the scheme presented in [5], in which transmission is allowed only in specific Transmission Areas (TAs). 6 In this protocol, we assume that the TAs are regularly spaced on the road, one every R meters. The region of radius R/2 around each transmission area is defined to be the cell associated with that TA.…”

Abstract-We consider medium access control (MAC) protocols for mobile ad hoc networks that are designed for MAC layer broadcasts. For example, such protocols could be used to transmit traffic information among vehicles. We analyze the performance of two simple MAC protocols, when multi-user interference is explicitly modeled via the received signal-to-interference plus noise ratio (SINR). One protocol is a simple slotted Aloha protocol with spatial reuse; the second protocol uses location information to determine the channel access. For both protocols we focus on a one dimensional model and measure performance in terms of the average number of nodes that receive each message in one hop.
