The efficiency of Point-To-Point (PTP) connections in ad hoc networks highly depends on the capability of the Medium Access Control (MAC) layer to reuse the shared wireless resource. One of the most critical impairments to the reuse capability is the exposed terminal problem which may prevent feasible PTP communications to run in parallel. In this paper we evaluate the impact of the exposed terminal on the reuse efficiency of PTP communications in ad hoc random networks. To this end, we propose a scheduling algorithm for PTP connections within the framework of ADHOC MAC, a recently proposed MAC scheme. The simulative results we gather show that the solution of the exposed terminal problem provides a reuse efficiency gain around the 40% in the network scenario we considered.

Abstract

The efficiency of Point-To-Point (PTP) connections in ad hoc networks highly depends on the capability of the Medium Access Control (MAC) layer to reuse the shared wireless resource. One of the most critical impairments to the reuse capability is the exposed terminal problem which may prevent feasible PTP communications to run in parallel. In this paper we evaluate the impact of the exposed terminal on the reuse efficiency of PTP communications in ad hoc random networks. To this end, we propose a scheduling algorithm for PTP connections within the framework of ADHOC MAC, a recently proposed MAC scheme. The simulative results we gather show that the solution of the exposed terminal problem provides a reuse efficiency gain around the 40% in the network scenario we considered.
