“…22 By analyzing the relation between the throughput and the packet dropping probability of the wireless channel, a jointing adaptive modulation was designed to improve the throughput with guaranteed low and tolerable packet dropped probability. 23 By observing and evaluating the interaction pattern of nodes in network, reputation-based strategies identify which node is the selfish one. A node can adopt a different strategy by checking others reputation values when they meet each other.…”

It is expected that all the nodes try their best to store and forward the messages in the intermittent connection network. However, due to the limited resources, such as memory, power, and transient communication chance, selfish nodes may relay the messages without responsibility. Stimulating selfish to behave normally could improve network performance. However, usually, it is difficult to distinguish the selfish behavior from the inability to relaying the message. By monitoring the behavior of relay nodes that messages are forwarding through, this article proposes a scheme that relays messages according to the reputation of intermediate nodes. The proposed reputation estimation scheme combines selfish behavior and inability behavior, and reveals very little private information for the protocol practice. There is a trade-off between the threshold and the performance. Too low value may not distinguish the selfish nodes. On the contrary, some normal nodes may excluded and cannot join the relaying and processing. Simulation effectively demonstrates that the reputation affects the node’s performance, and an appropriate reputation threshold value is useful for improving the network performance.

This paper presents a combination of power control and adaptive modulation performance in wireless sensor networks (WSN). WSN comprised numerous smart and small sensor nodes with limited power, memory, and processing. Furthermore, there is an impairment wireless channel between the sensor node and the coordinator node. Energy and spectral efficiency are essential issues in WSN. These two targets can be reached by applying a combination of power control and adaptive modulation. This work proposes a power control system to determine the modulation level through feedback SNR value of instantaneous wireless channel condition. The modulation level continuously changed based on the wireless channel condition. This adaptive modulation increases spectral efficiency. A better channel condition will drive to switch into a higher modulation level and vice versa. The result shows that the existence of power control can increase by about 9% of spectral efficiency than a system without power control. The system without power control just has a 91 % of selection probability, while the system equipped with power control creates a 100 % selection probability at the same of modulation level (16 QAM). Besides, combining power control with adaptive modulation also adjusts transmitting power at sensor nodes so that the effective use of transmitting power at the sensor node can be achieved. Combining power control and adaptive modulation can decrease the power consumption, enlarge the spectral efficiency with specific target bit error rate (BER), reduce the interference level, and significantly improve the WSN system performance.

“…When the instantaneous signal-to-noise ratio (ISNR) is high, we can increase the rate of channel encoder to reduce parity bits as well as increasing the constellation size [5]. In all previous studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], only the MCS is adapted to ISNR. The AMC technique can be improved when combined with Cooperative Diversity (CD) [16][17][18][19][20][21][22].…”

In this paper, we propose two adaptive cooperation protocols for wireless systems. The first protocol chooses between cooperative communications (CC) and non-cooperative communications (NCC), the protocol that offers the highest instantaneous throughput. The best relay is activated only if the instantaneous throughput of relayed link is larger than that of direct link. The second protocol chooses between CC and NCC, the protocol that maximizes the average throughput. The best relay amplifies the received signal only when the average throughput of relayed link is larger than that of direct link. Both protocols include adaptive modulation and coding to increase the throughput by selecting the appropriate modulation and coding scheme. The results are valid for Rayleigh fading channels where relay nodes use amplify and forward relaying.
