IEEE 802.15.8 develops the specification of PHY and MAC for the peer aware communication (PAC) network, which is an infraless area network supporting low power wireless peer group communication. For providing efficient synchronized group communication, the PAC MAC superframe and cyclic-superframe structure are proposed. The devices of a PAC group can sleep and wake up synchronously at specific periods with preempted resources for supporting required quality of peer group services. Contention on access among neighbor peer groups can be avoidable implicitly by selecting a start time of peer group communication. The implicit contention avoidance control of cyclic-superframe structure is evaluated.
