Networks with cognitive packets

Abstract: Based on our earlier work ("Towards networks with intelligent packets", Proc. 14th Int. Symp. on Computer and Information Sciences, p. 1-11, Oct. 1999), we discuss packet networks in which intelligent capabilities for routing and flow control are concentrated in the packets, rather than in the nodes and protocols. This paper describes a possible testbed to test and evaluate their capabilities, and presents an analytical model for the worst and best case performance of such systems.

Method and apparatus for dynamic bandwidth adaptation

Abstract: A dynamic bandwidth adaptation (DBA) algorithm is provided, such as for RTP/UDP/IP-based 2.5 G and 3 G wireless streaming systems. The DBA algorithm enables steady streaming quality and smooth transitions during congestion and network resource fluctuation periods, by automatically adjusting the video or audio bit rate stream to suit a changing bandwidth of a channel. The DBA algorithm monitors the channel for statistically significant and persistent changes in the bandwidth that may be associated with packet loss, delay, or delay variation. When these changes occur and when there is an existing closely matching but lower bit rate stream, the streaming server switches over to that lower stream. Switching to a higher bit rate stream may also be performed. Base delay or delay variation tracking information is used to further determine, improve, and optimize bandwidth adaptation. Data from a pause event is not collected, thereby improving the statistical analysis and decision-making process related to actual streaming.

Signaling cost and performance of SIGMA: A seamless handover scheme for data networks

Abstract: Department of Technology Education, Korea National University of Education, San 7-1, Darakri, Chongwon-Gun, Chungbuk, 363-791, KoreaSummaryMobile IPhasbeendeveloped to handlemobility of Internet hosts at thenetworklayer.MobileIP(MIP),however,suffers from a number of drawbacks such as requirement of infrastructure change, high handover latency, highpacket loss rate, and conflict with network security solutions. In this paper, we describe and evaluate theperformance of SIGMA, a Seamless IP diversity-based Generalized Mobility Architecture. SIGMA utilizesmultihoming to achieve seamless handover of mobile hosts, and is designed to solve many of the drawbacks ofMIP, including requirement for changes in infrastructure. We first evaluate the signaling cost of SIGMA andcomparewiththatofhierarchicalMobileIPv6(anenhancementofMobileIP)byanalyticalmodeling,followedbycomparison of handover performance of SIGMA and Mobile IPv6 enhancements. Criteria for performanceevaluation include handover latency, packet loss, throughput, and network friendliness. Our results indicatethat in most cases SIGMA has a lower signaling cost than Hierarchical Mobile IPv6. Moreover, for a typicalnetwork configuration,SIGMA hasahigherhandoverperformanceoverMobileIP.Copyright#2005JohnWiley& Sons, Ltd.KEY WORDS: mobile handover; SIGMA; mobile IP; IP diversity; signaling cost1. IntroductionMobile IP (MIP) [1] has been designed to handlemobility of Internet hosts at the network layer tomanage mobile data communication. It allows aTCP connection to remain alive when a mobile host(MH) moves from one point of attachment to another.Several drawbacks exist when using MIP in a mobilecomputing environment, the most important onesidentified to date are high handover latency, highpacket loss rate [2], and requirement for change ininfrastructure. MIP is based on the concept of homeagent (HA) and foreign agent (FA) (which requiresmodificationtoexistingroutersinInternet)forroutingpackets from previous point of attachment to the newone. An MH needs to complete the following foursteps before it can receive forwarded data from theprevious point of attachment: (i) perform layer 2 (L2)handover, (ii) discover the new care of address (CoA),(iii) registering the new CoA with the HA, and (iv)

Mitigation of black hole attacks in Routing Protocol for Low Power and Lossy Networks

Abstract: Routing Protocol for Low Power and Lossy Networks (RPL) has been standardized by the Internet Engineering Task Force to efficiently manage the functions of the network layer when providing Internet connectivity for wireless sensor networks RPL has been designed for constrained devices and networks Owing to their constrained nature, RPL-based networks can be exposed to a wide variety of security attacks One of the most serious attacks in RPL is a black hole attack, where a malicious node silently drops all the packets that it is supposed to forward This paper proposes a mitigation technique against black hole attack with low packet loss and high reliability The proposed technique consists of a local decision and a global verification process First, each node observes the communication behavior of its neighboring nodes by overhearing packets transmitted by its neighbors and attempts to identify suspicious nodes based on their behavior In the second process, if a node identifies a suspicious node, then it verifies whether the suspicious node is a black hole We demonstrate that the proposed approach increases packet delivery rate significantly and detects black hole attack effectively Copyright © 2016 John Wiley & Sons, Ltd
