摘要：This paper addresses a protocol dedicated to Internet of Things wireless collecting network. Such network collects data from large static systems such as bridges, roads buildings or mobile like materials, products or people transport systems. The purpose of this data collection is to monitor the system in order to enhance security and maintenance procedures. Low energy consumption is required from sensor nodes due to the cost and working time to change or recharge batteries. According that data are not locally processed and for a given type of electronics and node architecture energy consumption vary with two parameters: emission duration and reception duration. The proposed TOMAC-WSN-Eco protocol reduced both parameters at the minimum values by avoiding collision and waking up receiver component just when it is needed. All operations are formally defined. Performance and energy consumption are calculated. Various simulations give also performance evaluation. The results show that the proposed TOMAC-WSN-Eco protocol is particularly sober while satisfying the imposed quality of service constraints.
