Environment-Aware CMT for Efficient Video Delivery in Wireless Multimedia Sensor Networks

Abstract

Wireless Multimedia Sensor Networks (WMSNs) have gained significant attention with capabilities of retrieving video and audio streams, still images, and scalar sensor data but with challenge of high data loss. As more and more wireless devices are equipped with multiple network interfaces, multimedia delivery over multipath has been cognized as a more promising approach in wireless transmission. In this paper, based on the Concurrent Multipath Transfer (CMT) extension for Stream Control Transport Protocol (SCTP), we propose a novel environment-aware CMT (e-CMT) to overcome the high data loss challenge, as well as "a hot potato" congestion problem in wireless transmission. The e-CMT provides environment-aware cognitive ability for efficient video delivery with three modules, which are Path Quality-aware Model (PQM) that devotes to estimate path quality and select candidate path using for retransmission, Adaptive Retransmission Trigger (ART) that contributes to cognize packet loss and trigger efficient retransmission behaviors, and Congestion-avoid Data Distributor (CDD) that serves to enable Partial-Reliable retransmission to mitigate congestion condition. We design a close realistic topology to present how the e-CMT outperforms the original CMT for efficient video delivery over multihomed WMSNs.

Cognitive Adaptive Access-Control System for a Secure Locator/Identifier Separation Context

“…Our future work will embed the DHT-ADS into the CAAC then evaluate and analyze the performance of the CAAC system. Moreover, since the locator/identifier separation is a good standard selection for multi-homed network as mentioned in Section 1, thus our future work will focus on extending the CAAC for optimizing the communication capability with our previous work [18][19][20][21][22][23][24][25][26], and further evaluate and analyze its performance with realistic network traffic.…”

Qos-driven SCTP-based multimedia delivery over heterogeneous wireless networks

“…Complex behaviors of Internet traffic are necessary for transport protocol performance testing. The Internet survey mentioned in [12] claimed that TCP and UDP traffic on the Internet are about 80%-83%…”

“…Although large numbers of SCTP path selection schemes [9][10][11][12][13][14][15][16] and handover solutions [17][18][19][20][21][22][23][24][25] have been introduced, there is still significant ongoing work addressing many problems of the SCTP handover. In current SCTP handover solutions, each candidate network is evaluated as a function of multiple transport layer attributes.…”

Fuzzy-Based Trust Prediction Model for Routing in WSNs

“…Wireless sensor networks (WSNs) have attractive wider range of application from civil sector to military [ 1 – 5 ]. A WSN consists of large number of resource constraint sensor nodes (SNs) deployed in hostile environment which makes it feasible for adversaries to perform varied types of attack [ 6 , 7 ].…”
