Push-to-talk (PTT) is a promising service for group-based voice communication in ad-hoc networks that organize communication groups. Previously proposed iPTT mechanisms use a cluster-based super node for call determination. However, a hierarchical structure that uses clusters introduces unnecessary signaling costs, while an ad hoc network is vulnerable to energy consumption. To solve these challenges, this paper proposes a proxy-based energy efficient peer-to-peer push-to-talk (ePTT) service mechanism for ad-hoc networks. Through analysis of the performance of two schemes, we confirmed that the proposed ePTT is superior to iPTT in terms of signaling costs for overlay network construction and call determination.
