TL;DR: In this paper, cluster-based routing mechanisms for wireless sensor networks are analyzed and cluster head selection, cluster formation and data transmission are three key techniques in cluster- based routing protocols.
Abstract: Routing technology at the network layer is pivotal in the architecture of wireless sensor networks. As an active branch of routing technology, cluster-based routing protocols excel in network topology management, energy minimization, data aggregation and so on. In this paper, cluster-based routing mechanisms for wireless sensor networks are analyzed. Cluster head selection, cluster formation and data transmission are three key techniques in cluster-based routing protocols. As viewed from the three techniques, recent representative cluster-based routing protocols are presented, and their characteristics and application areas are compared. Finally, the future research issues in this area are pointed out.

TL;DR: The main idea is to use a 'traffic profile' of the network, obtained by measurements or service-level agreements as a rough predictor of the future traffic distribution, to solve a multi-commodity network flow problem, whose output is used both to guide the online path-selection algorithm as well as to impose admission control.

TL;DR: Analyzing three routing protocols for ad hoc networks using the GloMoSim simulation environment shows that STAR achieves better overall performance than AODV and DSR in sparsely connected networks and for densely connected networks, while STAR performs much better in terms of control overhead.
Abstract: Many routing protocols for ad hoc networks have been proposed to date. Among them, STAR (source tree adaptive routing protocol) is a representative table-driven protocol, while AODV (ad hoc on-demand distance vector protocol) and DSR (dynamic source routing protocol) are two representative on-demand protocols. This paper analyzes these three protocols using the GloMoSim simulation environment. The scenarios used in the simulation experiments take into account a variety of environmental factors that influence protocol performance. The performance of the protocols is compared in terms of their control overhead, amount of data delivered, and average latency in packet delivery. The simulation results show that STAR achieves better overall performance than AODV and DSR in sparsely connected networks. For the case of densely connected networks, AODV performs better in terms of data delivery, while STAR performs much better in terms of control overhead. The study also addresses the question of how accurate a simulator could be regarded for presenting the characteristics of the routing protocols and for comparison purposes.

TL;DR: The HOLSR mechanism is derived from the O LSR protocol; however, unlike OLSR, the HOLSR protocol takes advantage of different mobile node capabilities to reduce the routing control overhead in large heterogeneous ad hoc networks, thus improving the performance of the routing mechanism.
Abstract: This article reviews the hierarchical optimized link state routing (HOLSR) mechanism for heterogeneous mobile ad hoc networks. In this work a heterogeneous mobile ad hoc network is defined as a network of mobile nodes that are characterized by different communications capabilities, such as multiple radio interfaces. The article focuses on proposing the HOLSR protocol. The HOLSR mechanism is derived from the OLSR protocol; however, unlike OLSR, the HOLSR protocol takes advantage of different mobile node capabilities to reduce the routing control overhead in large heterogeneous ad hoc networks, thus improving the performance of the routing mechanism.
