CSRS-MAC: Cluster Based Synchronous Radio Scheduling MAC Protocol Using Carrier Sense Multiple Access for Wireless Sensor Network

Wireless sensor network is gaining popularity due to its large-scale deployment in Internet of Things. The constraints of resources influence the protocol design at every layer. The management of radio scheduling takes place at physical layer by means of suitable design of MAC protocol to ensure optimal use of energy. The optimization takes place by synchronizing the carrier sensing multiple access mechanism. The traditional MAC protocol like IEEE-802.15.6 with CSMA is delays intensive as well as consumes more energy. Therefore, this paper introduces an analytical modeling of cross layer design approach of MAC protocol with clustering to ensure better network performance and prolonged lifetime with optimal use of energy. The average packet delay of the proposed MAC protocol as synchronous radio scheduling(ProP-SRS) reduces by 14 and 0.77% with respect to the S-MAC and Q-MAC respectively, whereas, The energy utilization for transferring per bit of data of the ProP-SRS reduces by 39.32 and 1.78% with respect to the S-MAC and Q-MAC respectively. The trend of the average packet delay for a MIAT = 4 with varying value of the slot exhibit lower trend for the Prop-SRS, whereas Q-MAC is immediately inferior and S-MAQ provide higher delay. The trend of the energy utilization per bit with varying value of the slot exhibit lower trend for the Prop-SRS, whereas Q-MAC is immediately inferior and S-MAQ comes higher energy per bit.
