“…Thus, in most situations, the transmission power used by the ARPC MAC is close to that used by the OTP scheme. Simulation results in [15] further showed that the difference between the system throughputs induced by the RTRC scheme and the SCRC scheme (and hence the OTP scheme) is negligible. Since both the ARPC MAC and the OTP MAC were designed with the same principle (as the IEEE 802.11 DCF) but TPC schemes, they are comparable in system throughput.…”

“…In [15], another MAC protocol, named ARPC (adaptive range-based power control), was proposed. The ARPC MAC adaptively selects one of three TPC schemes: receiver carriersensing range cover (RCRC), sender carrier-sensing range cover (SCRC), and receiver transmission range cover (RTRC).…”

“…The CSR concerned TPC schemes, e.g., [9][10][11][12][13], shrink the CSR areas to certain extents by lowering the transmission powers until the receiving nodes can recognize their packets only when there is no interference. On the other hand, the IR concerned TPC schemes, e.g., [14,15], shrink the IR areas to certain extents by raising the transmission powers until the IR areas can be covered by the CSR areas. However, the SIR concerned TPC schemes, e.g., [16,17] , which are neither CSR concerned nor IR concerned, try to maintain the SIR values of those simultaneous transmissions.…”

“…In the recent decade, a great number of works, e.g., [6][7][8][9][10][11][12][13][14][15][16][17], were dedicated to improving the throughputs of IEEE 802.11 wireless ad hoc networks, in order to meet the increasing needs of high bandwidths. Although the approaches in [6][7][8] can enhance the throughput, they require two transceivers and two channels, which increase the hardware complexity and hardware cost at the same time.…”

In this paper, we introduce the concept of ceased areas for enhancing the spatial reuse in CSMA/CA based wireless ad hoc networks. Intuitively, a ceased area is created by a transmitter-receiver pair where all other nodes are required to keep silent. The size of a ceased area depends on the transmission power and the transmitter-receiver distance. A new transmission power control (TPC) scheme that can minimize the induced ceased area is proposed. And it is superior to previous TPC schemes in throughput.

Owing to retransmission of lost packets and bursty nature of source data, even an ad hoc network with low average traffic may suffer heavy traffic in some certain periods, which in further may degrade system performance, particularly in multi-hop wireless communication. Aiming to provide a solution to above problem, in this paper, we construct a hybrid system based on plural ad hoc networks, which are defined as primary radio networks (PRNs), and a secondary radio network (SRN). In the hybrid system, a cooperative relay scheme based on dynamic spectrum access, defined as cognitive relay, is adopted for retransmitting the lost packets of PRNs. Cognitive relay is carried out by SRN in spectrum hole. Simulation-based evaluation shows that the proposed cognitive relay, com pared to existing retransmission protocol, is more effective in providing QoS-guaranteed communication.

IEEE 802.11 distributed coordination function (DCF) is a popular protocol used for the physical and medium access control layers in most ad hoc networks. DCF employs carrier sense multiple access with collision avoidance and a binary slotted exponential back off. It has been observed that the hidden and exposed terminal problems among stations degrade DCF's performance in terms of throughput and fairness. Hence, the effectiveness of the IEEE 802.11 DCF mechanism in ad hoc networks has attracted many research studies. Many collision avoidance schemes were proposed to address the IEEE 802.11 DCF weaknesses as the performance of the medium access control layer directly impacts the performance of higherlayer protocols and hence the entire network. An evaluation of representative schemes under the same conditions will be helpful in understanding the limitations and strengths of these schemes. This paper surveys various collision avoidance schemes, classify them on the basis of their mechanism, and then provide a comparative study of representative schemes based on their performance. They are evaluated on a chain topology, a pair topology, and a random topology with static environment to measure their throughput, fairness, collision probabilities, and delay. On the basis of the evaluation, we conclude that gentle DCF is the best scheme that has lesser collisions with improved throughput and fairness. A comparison with the legacy carrier sense multiple access with collision avoidance suggests that these proposed schemes do tend to be promising and would inspire future researchers who are interested to find solutions to the age-old collision and fairness issues in ad hoc networks. reducing the lifetime of battery-powered wireless devices.The problem of collisions is worse in a multi-hop environment than in a single-hop environment [2]. CA is implemented in the MAC layers. A MAC protocol should provide an effective mechanism to share the available limited spectrum resources while delivering high throughput and fairness to all the stations [3].In the past few years, multiple MAC protocols were developed to improve throughput, fairness, delay, and CA. A MAC protocol can be contention or reservation based. Contention-based MAC protocols are used for applications requiring bursty traffic under a light network load and low delay. A reservation-based MAC protocol is generally used for applications with real-time requirements provid-
