TDMA-based multi-hop resource reservation protocol for real-time applications in tactical mobile adhoc network

Abstract

This paper proposes a new time division multiple access (TDMA) based multi-hop resource(slots) reservation protocol (TMRR) for tactical mobile adhoc networks (T-MANET). TMRR lets a node reserve the channel resource for multi-hop packet transmission in consecutive order, so that the packet transmission between a source node and a multi-hop away destination node is possible within a superframe. This paper evaluates the performance of the proposed protocol via OPNET simulation in terms of the average end-to-end delay and the average throughput in both static and mobile environments. And this paper compares it to that of the Evolutionary-TDMA (E-TDMA) which is a representative reservation-based medium access control (MAC) protocol considering node mobility in MANET. According to the simulation results of the single-hop scenarios, TMRR gives better packet throughput and delay performance than E-TDMA as the offered traffic is increased. For the multi-hop scenarios, the average end-to-end delay of TMRR nodes meets the multi-hop end-to-end delay requirements because a node can transmit the packets to a multi-hop away node within a superframe.

Intelligent cognitive spectrum collaboration: Convergence of spectrum sensing, spectrum access, and coding technology

“…To solve the problem of spectrum access in dynamic networks, many methods can implement dynamic spectrum access, including competition algorithms (such as ALOHA [46] and CSMA [47] ), reservation algorithms (such as FPRP [48] and NbIA [49] ), and the queuing algorithms (such as DLPS [50] ). With the development of evolutionary algorithms, including GA [51,52] , PSO [53] , and biological foraging algorithms [54] , researchers are increasingly trying to integrate their use in dynamic spectrum access.…”

Primary Path Reservation Using Enhanced Slot Assignment in TDMA for Session Admission

“…In [18], the proposed TMMR protocol performs bandwidth reservation in order to attain multihop packet transmissions. It also provisions the node mobility through fast fault node detection.…”

“…As shown, we obtain higher throughput while using PRAC. However, when St backup [13] and DACP [25] are used, only medium throughput is obtained and when TMMR [18] is used, only lower throughput is obtained. From the results it is clear that the proposed protocol is capable of reducing the number of unnecessary routing packets during route discovery, by making admission control decisions at every node in the network.…”

“…There are many reservation based protocols, such as hop reservation multiple accesses (HRMA) [15] and five-phase reservation protocol (FPRP) [16, 17]. In addition, contention based protocols, such as carrier sensing multiple accesses with collision avoidance (CSMA/CA), and hybrid protocols, such as TDMA protocol based on contention and reservation [18], exist. The reservation based TDMA protocols have several advantages over contention based protocols, of which conflict free and maximum spatial reuse efficiency is acquainted to the domain [14, 19, 20].…”

Group Connectivity-Based UAV Positioning and Data Slot Allocation for Tactical MANET

“…In [1], a QoS-attaining scheme considering energy efficiency was proposed. In [18], a TDMA-based multihop resource reservation (TMRR) scheme was proposed for flow-based slot scheduling in order to minimize end-to-end delay, and the slot information in a beacon slot is exchanged in every frame. In [19], a contention-based slot allocation scheme, that reflects topology changes and traffic demand, was proposed.…”
