ns-2 Implementation of the OMA PoC Control Plane
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
Recently technologies such as VoIP, VoLTE and VoWLAN have been widely used for the purpose of voice conversation since the proliferation of smart phones. A half-duplex group communication or the push-to-talk (PTT) has been standardized under the Open Mobile Alliance to replace the existing analog/digital TRS or a walkie-talkie service. In this paper, we design and implement the ns-2 module of the OMA PoC control plane which is a signaling protocol for the PTT service. Based on the SIP implementation of Rui Prior, we extend it to simulate the ad hoc PoC session establishment using on-demand session, which is a signaling protocol according to the rules and procedures of RFC 3261 with extended headers including PoC feature tags. Some simulation results have been shown for the verification purpose using the proposed implementation. With this implementation, we expect to perform the extensive simulation study of group communication in various network configuration
