“…They identified the optimal intrusion detection rate and the optimal regional area size under which the mean time to security failure of the system is increased and/or the total communication cost is decreased for GCSs, given a set of parameter values characterizing operational and environmental conditions. Jin-Hee Choa et al [18] have proposed a scalable and efficient region-based group key management protocol for securing group communications. They considered a regionbased approach for providing scalability and dynamic re-configurability.…”

“…Several recent works investigated the group key management for scalability and energy efficiency performance in MANETs as in [15][16][17][18]26,27]. In [15], Zhu et al studied the flexibility and scalability of dealing with risks in the practical usage of ad hoc networks and proposed a hierarchical scheme based on threshold cryptography to address both security and efficiency of key management in MANETs.…”

In [16], Cho et al proposed a scalable and efficient group key management protocol for secure group communications in MANETs and identified the optimal settings of the key management protocol to minimize the network traffic as well as to efficiently balance intergroup vs. intra-regional group key management overheads. Based on it, in [17], Cho et al integrated the above group key management protocol with intrusion detection to handle both outsider and insider security attacks for group communication systems (GCSs) in MANETs.…”

Network security and its energy efficiency are facing tougher challenges for mobile ad hoc networks (MANETs) due to emerging purposive strategic internal attacks conducted by smart malicious nodes and unavoidable external attacks. Most of the current works investigated the group key management for scalability and efficiency performance in MANETs to defend the external attacks, while some works envisioned the intrusion detection system or trust management to defend the internal attacks. However, fewer related protocols or algorithms could combine them well to enhance dual security performance as well as energy efficiency in MANETs. To this end, we have proposed a novel group key management protocol with high energy efficiency for the strategic mobile scenario of MANETs, which is provided with three functions to address the issues of improving security and energy efficiency performance: (1) designing a self-organized group establishing algorithm for strategy mobile application scenarios to ensure stable groups in spite of users' mobility with reducing the cost of rekeying operation, (2) proposing a lightweight contributory key agreement and authentication mechanism based on the group Diffie-Hellman protocol for enhancing global security, and (3) researching a strategic mobile management mechanism based on the Prufer codec method handling the effect of mobility impacts to enhance the multicast energy efficiency and provide secret communication among roaming users in MANETs. Both theoretical analyses and simulation results have demonstrated that our protocol is more energy-efficient for strategy mobile application scenario of MANETs with a large number of users.

“…Further, each node's capacity to disseminate packets per second is limited by its "average workload." We adopt a hierarchical network structure [5] for scalability by having a leader in each region, called "regional leader". For any communications between two nodes in two different regions, including communications for auctioning, a packet is disseminated through the hierarchical structure such as noderegional leader -regional leader -node.…”

Abstract-This paper proposes a combinatorial auction based approach to solving a multiple dynamic mission assignment (MDMA) problem. The problem presents itself in scenarios in which mobile nodes perform multiple missions, and the missions are supported by multiple nodes in a mobile ad hoc network. In this scenario, missions may dynamically arrive, may have to be completed at different times, and different numbers of members may be required for mission execution. The proposed MDMA protocol aims to minimize communication overhead caused by the mission assignment while maximizing each node's utilization (i.e., minimizing its idle time) and maximizing the fraction of mission completion over the initial missions given. We compare the proposed MDMA protocol with baseline mechanisms such as a single-item auction or a single-minded auction based on the above performance metrics.
