A Routing Algorithm of Multiple Objective GA Based on Pareto Optimality

Survey of QoS Routing Protocols in Wireless Multimedia Sensor Networks

“…(v) Bandwidth. Bandwidth indicates bit rate of the available or consumed data capacity that can be used to send data over a link or a path in a given period [36,41,45,59,[64][65][66].…”

“…(xiv) Jitter. Jitter represents packet delay variation or latency variation over time, which results in fluctuating packet interarrival times [65,66]. A network with a consistent delay will have no jitter; however, with variable delay, it will have high jitter.…”

“…Packet loss rate represents the number of packets lost with respect to the number of packets sent. Packets are lost due to congestion or due to a damaged link [37,51,55,59,62,66]. Packet loss rate is an important metric for measuring the performance of routing protocol.…”

“…Dual-metric Triple-metric Quartet-metric Five and more-metric link/path cost-dependent protocols [19] [20], [21], [22], [23], [24], [25], [26], [27], [28], [44], [45], [46], [47], [48], [49], [64], [67] [29], [30], [31], [32], [33], [34], [35], [36], [50], [51], [52], [53], [54], [65], [68], [69] [37], [38], [39], [40], [41], [55], [56], [57], [58], [59], [60], [61], [66] [42], [43], [62], [63] link/path costdependent protocols link/path costdependent protocols link/path cost- link/path cost-dependent routing protocols.

“…Work by Dong et al based on the genetic algorithm finds the best routing path from the set of Pareto-optimal routing paths [66]. These paths are found with a multiobjective function that is based on four metrics, namely, bandwidth, delay, jitter, and packet loss rate.…”
