They also have limited memory and limited computational power. The challenge of a network based on such constrained infrastructure is twofold; maintaining data reliability and energy efficiency. Availability of the instantaneous channel side or state information (CSI) at the transmitter can help it to set transmission parameters, such as power, data rate and encoding technique, to achieve optimum results. However in an indoor environment, when the movement of objects between a transmitter and a receiver is random, the estimated CSI may not be sufficient to obtain desired results. This paper evaluates the impact of channel fading on data reliability due to multipath transmission. Simulation results q the number of retransmissions required for an indoor fading channel and its impact on battery life. Although adaptive transmission techniques have been proposed and implemented to maximize throughput in several technologies including WIMAX, the primary focus of this paper is on research related to improve energy efficiency of sensor nodes rather than throughput. This is because sensors used for surveillance and monitoring are not designed for high data rates, but are meant to send data to the central station with a certain threshold bit error rate and acceptable latency. This paper proposes a transmission strategy to increase energy efficiency of fading radio channels for improved data reliability. It also emphasizes the need to introduce an opportunistic transmission strategy to meet these goals.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131681928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are three main forces driving the LR-WPAN community to expand its operational band to the TVWS. First, the change in TVWS-related regulations that opens up new spectrum resources is the key triggering factor. Secondly, there are many potential applications addressed by LR-WPAN systems that are anticipated to benefit from the expansion of the spectrum. Thirdly, the emergence of multiple standardizations targeting on the same types of applications in the same conventional frequency bands, indicating potential congestion and heterogeneous coexistence issues, is also one of the main pushing factor. In this paper, a comprehensive summary of different regulations, list of potential usage models and interactions among conventional LR-WPAN system are presented. A general discussion on how these factors fall in place to realize the forming of IEEE 802.15.4m is given. Finally, the paper concludes with expected functional requirements for the IEEE 802.15.4m system.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126900428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such a situation, wireless multimedia services have spread widely over MIMO-OFDM systems. How to provide user-satisfied multimedia services over MIMO-OFDM systems has attracted increasingly attentions. Quality of experience (QoE) is the key criteria for evaluating users' satisfaction with multimedia services in terms of mean opinion score (MOS). In this paper, we propose a QoE-driven cross-layer optimized video transmission scheme over MIMO-OFDM systems. No-reference QoE estimation model is applied to acquire the expected MOS taking account of video content type (CT), frame rate (FR), video sending bit rate (SBR) and packet error rate (PER). The aim of our proposed scheme is to achieve user-satisfied video quality by jointly optimizing video coding parameters at the application layer and modulation and coding scheme (MCS) at the physical layer. The problem is formulated to find the optimal combination of parameters to maximize expected MOS with constraint of maximum transmission delay, and solved by improved traversal algorithm. Experimental results have shown significant performance enhancement of the proposed system based on H.264/AVC and NS2.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114491045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, real time multimedia services still provide challenges as reliable delivery of the content cannot be guaranteed. The video compression standards incorporate error resilient mechanisms to mitigate this effect. However, these methods assume a packet-loss scenario, where corrupted slices are dropped and concealed by the decoder. This paper presents the application of reversible watermarking techniques to facilitate the detection of corrupted macroblocks. A variable checksum is embedded within the coefficient levels and motion vectors, which is then used by the decoder to detect corrupted macroblocks which are concealed. The proposed method employs difference expansion to protect the level values while histogram modification was employed to protect the motion vectors. Unlike previous published work by the same author, this scheme does not need the transmission of side information to aid the recovery of the original level and motion vector values. Simulation results have indicated that significant gains in performance can be achieved over the H.264/AVC standard.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125329858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
