“…Mobile ad-hoc networks are autonomous sets made up of a set of wireless users (nodes). It does not need the support of fixed base station, and there is no centre management and temporary organisation, and has a high degree of mobility, which can be widely used in military tactical communication, emergency communications, temporary communication and sensor networks, and other needs of rapid deployment, dynamic network communication applications [15][16][17][18].…”

The comprehensive performance of electric vehicles (EVs) and distribution of charging locations are two key factors restricting the development of EVs. An effective way to improve the performance of EVs is to manage the battery pack with a battery management system (BMS), while in the actual operation, the collection and analysis of the battery state parameters is of great significance to the study of BMS. It is necessary to detect and provide the location information of the nearest charging station, thus each vehicle is required to have network communication function because the vehicles may move in real time. The ad-hoc technology is used to solve the network communication between the vehicles and the charging piles. There is no standard routing protocol for ad hoc, and the network routing protocol directly determines the efficiency, reliability and correctness of the network data transmission. Based on the cluster-tree and ad-hoc on-demand distance vector junior (AODVjr) protocols, this study proposed a routing protocol suitable for mobile ad-hoc network algorithm, and made a simulation on the NS2 platform. The results showed that compared with other protocols, the ad-hoc routing protocol is more suitable for the application of this system.

“…Thus, requiring a complete change of the initial standard design, including explicit messages for association and feedback. In contrast, in [16] , the authors propose to use the active period of the superframe to transmit beacons in order to reduce the beacon collision probability, motivated by the fact that the active period is longer than the specified fraction of time devoted to transmit beacons in IEEE 802.15.4e. However, even though the collision probability of beacons is reduced in this way, beacon collision-free operation is not ensured and as in the previous approaches, a substantial change of the standard is needed, i.e., the fraction of time intended for beacon transmissions is no longer needed.…”

Beaconing is usually employed to allow network discovery and to maintain synchronisation in mesh networking protocols, such as those defined in the IEEE 802.15.4e and IEEE 802.11s standards. Thus, avoiding persistent or consecutive collisions of beacons is crucial in order to ensure correct network operation. Beacons are also used in receiver-initiated medium access protocols to advertise that nodes are awake. Consequently, effective beacon scheduling can enable duty-cycle operation and reduce energy consumption. In this work, we propose a completely decentralised and low-complexity solution based on learning techniques to schedule beacon transmissions in mesh networks. We show the algorithm converges to beacon collision-free operation almost surely in finite time and evaluate converge times in different mesh network scenarios.

“…A superframe starts at the beginning of a beacon frame and ends at the beginning of the next beacon frame. The superframe consists of an active and inactive period, and the coordinator will determine their lengths by set superframe order (SO) and beacon order (BO) to be 48× 2 SO UnitBackoffPeriods (UBPs) and 48 × (2 BO -2 SO ) UBPs respectively, where the UBP is equal to 20 symbols while a symbol is defined as the time that four data bits are transmitted [17].…”

A significant number of previous studies have shown, however, network traffic exhibited frequently large bursty traffic possesses self-similar properties. For the future applications of wireless sensor networks (WSNs) with large number of cluster structures, such as Internet of Things (IoT) and smart grid, the network traffic should not be assumed as conventional Poisson process. We thus employ ON/OFF traffic source with the duration of heavy-tailed distribution in one or both of the states instead of Poisson traffic to be as the asymptotically self-similar traffic for experimenting on the performance of IEEE 802.15.4 WSNs. In this paper, we will show the impact on the performance of IEEE 802.15.4 WSNs in different traffic sources such as Poisson and Pareto ON/OFF distribution by ns2 simulator. For the Pareto ON/OFF distribution traffic, we demonstrate that the packet delay and throughput appear bursty-like high value in some certain time scales, especially for the low traffic load; and the throughput will be no longer bursty-like while the traffic load increases. Intuitively, the bursty-like high delay may result in loss of some important real-time packets. For the Poisson traffic, both the throughput and packet delay appear non-bursty, especially for the high traffic load. Keywords-wireless sensor network (WSN); IEEE 802.15.4; self-similar traffic I.
