“…The congestion threshold should be determined before forwarding packets reasonably. To exploit the resources of a temporary link raised by node movement, the number of packets to be forwarded should be adjusted based on the current network state [16][17][18]. In this paper, we design an adaptive buffer partition method to well utilize the limited buffer resources.…”

Based on the “storing-carrying-forwarding” transmission manner, the packets are forwarded flexibly in Intermittently Connected Wireless Network (ICWN). However, due to its limited resources, ICWN can easily become congested as a large number of packets entering into it. In such situation, the network performance is seriously deteriorated. To solve this problem, we propose a congestion control mechanism that is based on the network state dynamic perception. Specifically, through estimating the congestion risk when a node receives packets, ICWN can reduce the probability of becoming congested. Moreover, due to ICWN’s network dynamics, we determine the congestion risk threshold by jointly taking into account the average packet size, average forwarding risk, and available buffer resources. Further, we also evaluate the service ability of a node in a distributed manner by integrating the recommendation information from other intermediate nodes. Additionally, a node is selected as a relay node according to both the congestion risk and service ability. Simulation results show that the network performance can be greatly optimized by reducing the overhead of packet forwarding.

“…Energy efficiency is a key requirement for the design of short‐range network. The paper by Zu Fan Zhang, Yin Xue Yi and Jing Yang entitled ‘Energy efficiency based on joint mobile node grouping and data packet fragmentation in short‐range communication system’ designed an energy‐efficient scheme‐based on joint mobile nodes (MN) grouping and data packet fragmentation, analyzed the energy efficiency corresponding to different packet length and group sizes, and established an appropriate energy consumption model. Simulation results show that, when mobile nodes of short‐range system are grouped by the proposed MN grouping algorithm and all nodes of each group are operating with the same size of data packet fragmentation, the short‐range communication system can provide significant energy savings.…”

“…D2D communication is an important part of heterogeneous networks. The spectrum efficiency, throughput and energy efficiency can be improved by interference suppression, resource allocation and relay selection schemes [ 5 , 6 , 7 , 8 ]. Many studies show that most researches on short-range communication systems focus on improving communication reliability and data rate among users [ 9 , 10 , 11 ].…”

The Device-to-Device (D2D) communication system is an important part of heterogeneous networks. It has great potential to improve spectrum efficiency, throughput and energy efficiency cooperation of multiple D2D users with the advantage of direct communication. When cooperating, D2D users expend extraordinary energy to relay data to other D2D users. Hence, the remaining energy of D2D users determines the life of the system. This paper proposes a cooperation scheme for multiple D2D users who reuse the orthogonal spectrum and are interested in the same data by aiming to solve the energy problem of D2D users. Considering both energy availability and the Signal to Noise Ratio (SNR) of each D2D user, the Kuhn-Munkres algorithm is introduced in the cooperation scheme to solve relay selection problems. Thus, the cooperation issue is transformed into a maximum weighted matching (MWM) problem. In order to enhance energy efficiency without the deterioration of Quality of Service (QoS), the link outage probability is derived according to the Shannon Equation by considering the data rate and delay. The simulation studies the relationships among the number of cooperative users, the length of shared data, the number of data packets and energy efficiency.
