“…For the RPGM model [20], we divided all nodes into four groups, with 25 nodes in each group. The node's MAC layer uses IEEE-802.11 DCF media access control protocol, the radio transmission range and the interference range of nodes are all set to be 200 m [21]. Each node has a total energy of 100J.Mobile nodes, and are assumed to move randomly according to the random walk, random waypoint, and RPGM mobility models.…”

MANET is an autonomous collection of distributed mobile nodes. Every node in a MANET works as a source and a sink and that relays packets for other nodes. The key features of a MANET include dynamic network topology, distributed network nature, multi-hop communication, limited bandwidth, and limited energy constraints. Given that the battery of the nodes is limited, the energy of the nodes and the lifetime of network is a critical problem in MANETs. Moreover, nodes maintain static or less movement after being deployed. The energy of the MANET nodes cannot be recharged, which leads to dead nodes. This study improves the energy cost for the ACECR and boosts advancement through its contributions. Areas in the ad hoc network where much work is needed are discussed. This study only explored the impact of PSO on ACECR. Results indicate that ACECR- PSO performed better than the other protocols in terms of balanced energy consumption and extended network lifetime.

“…Station 2 and station 3 which are arranged behind station 1 have only one time slot. Therefore, this algorithm loses the principle of impartial competition in DCF mode (Hans & Nayyar, 2014;Sun & Dai, 2014). The frequency band that IEEE 802.11b used is 2.4GHz.The channels that can be used and their number will be different for every area, and the maximum number is 14.The frequency band of each channel is 22MHz, and Non-Overlapping Channels is channel 1, channel 6 and channel 11 (Japan also has channel 14).…”

Many single-hop power management mechanisms have been proposed in previous studies. Compared to the multi-hop power management mechanisms, the design of the single-hop power management mechanism in a wireless network is relatively simple. However, existing methods are difficult to balance the transmission utilization and energy efficiency. This paper proposes the Contention-Free Station Communication Matching (CFSCM) algorithm for multi-hop power management. CFSCM is based on list-based scheduling with Time-Division Multiple Access (TDMA). CFSCM appropriately schedules the data transmission of nodes and power management. In addition, CFSCM adopts multiple channels to improve the performance of data transmission. Simulation results show that the proposed method can significantly improve transmission utilization and avoid the hidden terminal problems.

Chinese standards and foreign standards differ in technical indicators and requirements, which result in the poor recognition of products that comply with Chinese standards. It is crucial to set up a universal method to compare standard indicators, so that the inconsistency between standards could be eliminated, and ultimately improve Chinese products competitiveness. This paper proposed a method for indicator comparison from standards. Based on Semantic Web technology, the method introduced fragmentation of standard documents in a manner of ‘product stylistic rule indicator’ triplet. The processed fragments were annotated by the knowledge-based organization and used for the following indicator comparison. The method and procedure were generalized to develop standard indicator comparison system. The system provided a great experience in representing technical indicators as well as the comparison of indicators from standards. Further practice of the system suggested that repeated standard development and conflicted indicators in Chinese standards are still common.
