SUMMARY This Part-3 of the Special issue contains 5 papers, that are briefly discussed as
follows: The article “Tree-based Ant Colony Optimization Algorithm for Effective Multicast …

Background: Multimedia transmission over wireless communication is gaining momentum
with rapid use of mobile hand-held devices. Providing a QoS based routing solution is a …

The advent of ubiquitous computing and the proliferation of portable computing devices
have raised the importance of mobile and wireless networking. at the same time, the …

A multicast tree with a minimum cost is required to improve the quality of service (QoS)
constraints. Due to combinatorial issues, conventional approaches are not appropriate for …

The design of routing algorithm is very important for the network performance. Collective
intelligence of ants can be transformed in useful optimization techniques that can be …

Quality of Service is an indispensable parameter to evaluate the performance of any
network, so research engrosseson valuing some important QoS parameters for mobile …

An ad hoc network is a multi-hop wireless network formed by a collection of mobile nodes
without the intervention of fixed infrastructure. Multicasting is an efficient way of providing …

A mobile ad-hoc network is a self configuring network connected by wireless links. No
infrastructure or central administration is needed for these type of networks. Therefore, they …

ABSTRACT A wireless network topology that comprise heterogeneous routing paths without
the supported of any preliminary network infrastructure is known as a Mobile Ad Hoc …

In this paper, some improvements on Ant Colony Optimisation (ACO) are presented and we
use the improved algorithm to solve the multicast routing problem. The improvements are …
