Proposed MAC Protocol for M2M Networks

Abstract

Machine-to-Machine (M2M) communication is defined as the ability of machines to communicate without any human interaction. M2M network is expected to be widely utilized in many fields of Internet of Things (IOT) applications in which simplex (reservation - or contention based) Medium Access Control (MAC) protocols may not be able to provide a scalable solution for M2M networks with large number of devices. In this paper, a proposed MAC protocol for M2M Network will be suggested, which consists of a contention period and a transmission period. In this protocol, different devices contend on the transmission opportunities by using conventional based on Non - Persistent Carrier Sense Multiple Access (NP-CSMA) mechanism which is not clarified until now in M2M network. The successful devices only will be assigned a time slot for transmission during the transmission period depending on the reservation based Time Division Multiple Access (TDMA) mechanism. Moreover, comparisons between proposed MAC technique and other techniques such as Pure Aloha (P-ALOHA), Slotted Aloha (S-ALOHA), NP-CSMA will be made in terms of some parameters such as throughput, average delay time and Packet Delivery Ratio.
