[1] Distributed and Adaptive Medium Access Control for Internet-of-Things-Enabled Mobile Networks, APRIL 2017. Qiang Ye,Student Member, IEEE, and Weihua Zhuang, Fellow, IEEE

DOI  :  10.1109/JIOT.2016.2566659

Abstract—In this paper, we propose a distributed and adaptive hybrid medium access control (DAH-MAC) scheme for a single-hop Internet of Things (IoT)-enabled mobilead hoc network supporting voice and data services. A hybrid superframe struc-ture is designed to accommodate packet transmissions from a varying number of mobile nodes generating either delay-sensitive voice traffic or best-effort data traffic. Within each superframe,voice nodes with packets to transmit access the channel in a contention-free period (CFP) using distributed time division mul-tiple access, while data nodes contend for channel access in contention period (CP) using truncated carrier sense multi-ple access with collision avoidance. In the CFP, by adaptively allocating time slots according to instantaneous voice traffic load, the MAC exploits voice traffic multiplexing to increase the voice capacity. In the CP, a throughput optimization frame-work is proposed for the DAH-MAC, which maximizes the aggregate data throughput by adjusting the optimal contention window size according to voice and data traffic load variations. Numerical results show that the proposed MAC scheme outper-forms existing quality-of-service-aware MAC schemes for voice and data traffic in the presence of heterogeneous traffic load dynamics.

[2] A Game-Based Localized Multi-Objective Topology Control Scheme in Heterogeneous

Abstract—In wireless networks, network topology may change at any time. Therefore, topology control is one of the effective methods to get and keep the desired topology performance. The most existing topology control methods assume that nodes are altruistic. Although there are some game-based topology control schemes to stimulate cooperation between nodes, they only consider a single objective (e.g., energy consumption or network lifetime), which cannot be adaptive to the variation of demand on topology performance. To address these weaknesses, we present the notion of link lifetime and model the multi-objective weight sum of any link as the function with respect to transmission power, link delay and link lifetime. Then the proposed game-based localized multi-objective topology control ensures that the desired topology property exists in resulting topology, in which the presented Improved LOCAL -Improvement Algorithm (LDIA) algorithm not only stimulates nodes' cooperation on topology control operation and ensures network's convergence to a steady state, but also has the better performancewith respect to executing time and communication overhead than a classic algorithm, i.e., LDIA. Finally, the simulation results show that, by employing appropriate weight values, when compared with some typical schemes considering only energy ef ciency, the proposed scheme is the most ef cient in regard to average link delay and link lifetime. When compared with a typical scheme considering only network lifetime, the proposed scheme has advantage over average link lifetime, but it is slightly worse in terms of average link delay. Although

the proposed scheme is less ef cient in terms of average transmission power, where the shortage may be alleviated by adjusting weight values, it satis es diversi ed demands for applications due to its exibility.
