The problem of exposed terminals in AD Hoc results in wireless channel resource being wasted, which limits the network capability severely. By comparing with most solutions of this problem, we give new descriptions of exposed terminals and the exposed receive terminals. Then a concurrent transmission algorithm based on reverse path of route is proposed. By(More)
IEEE 802.11 DCF protocol exhibit severe fairness problem in many scenarios. In this paper, the reasons why fairness problem appears is given and proved by simulation. The study reveals that the interference among contending MAC flows is different when fairness problem happens. This paper consider that different interference between MAC flows cause the DCF(More)
UAVs Ad-Hoc Networks has earned more and more attentions recently. How to design a collision-free MAC protocol which allows UAVs to access the networks rapidly and reliably is a crucial challenge. Many MAC protocols proposed for VANETs or UAVs Ad-Hoc Networks have some limitations, i.e., some ones need full duplex technique which is not very practical now.(More)
Ad hoc social networks (ASNETs) are emerging as an important communication platform for mobile users. As a special kind of ASNETs, the construction of smartphone Ad hoc network has been extensively investigated. For smartphone Ad hoc network, development of various experimental network scenarios is essential for technical study. However, constructing a(More)
The proposed algorithm selects the path under reliability constraint with minimum total power consumption and maximum nodes¿ residual battery (RCEB) to balance energy and maximize the network lifetime. An evaluation function of objective optimization degree is formatted. A new heuristic algorithm with pseudo polynomial-time complexity is proposed to(More)
