Due to life threatening situations, timely sending of data is essential. In this study transmission delay of different paths, through which data is sent from sensor to health care center over heterogeneous multi-hop wireless channel is analyzed. Data of medical related diseases is sent through three different paths. In all three paths, data from sensors first reaches ZigBee, which is the common link in all three paths. Wireless Local Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunication System (UMTS) are connected with ZigBee. Each network (WLAN, WiMAX, UMTS) is setup according to environmental conditions, suitability of device and availability of structure for that device. Delay of data reaching each device is calculated and represented graphically. Main aim of this study is to calculate delay of each link in each path over multi-hop wireless channel.

Frame Aggregation

With the development of internet technologies and applications, video becomes the main source of online generated data. Real-time generated big data video on the internet have many challenges, which include broadcast, evaluation, storage, analysis, and transmission. For multimedia applications, processing and communication are important areas to realizing ambient intelligence and Quality of Service (QoS) is a major challenge for designing and implementation of processing and communication of multimedia traffic. In this study, simulation results have verified the possibility and effectiveness of the developed intelligent wireless QoS technology in terms of big data video communication over a Wireless Local Area Network (WLAN). Structural Similarity Index (SSIM) and Video Quality Metric (VQM) video quality matrixes are used for measurement of received video at receiver. The results show that dynamics frame aggregation mechanism improve the big data video delivery for SSIM and VQM in comparison to frame aggregation mechanism defined by the draft of IEEE802.11n WLAN.

This study evaluates video codec performance over VoIP using a campus wireless network. Today, the deployment of VoIP occurs in various platforms, including VoIP over LAN, VoIP over WAN and VoIP over VPN. Therefore, this study defines which video codec provides good video quality over VoIP transmission. The soft phone is used as a medium for communication between two parties. A network management system is used to evaluate and capture the video quality performance over VoIP. The quality of video codec is based on MOS, jitter, delay and packet loss. The experimental scope is limited to G.722 with MP4V-ES, G.726 (16) with H.261 and G.726 (24) with H.264. The results show that audio codec G.722 with MP4V-ES generates good video quality over VoIP using wireless local area network. Whereas audio codec G.726 (16) with H.261 generates low rate video and voice quality performance. Therefore, using the appropriate video and audio, the codec selection increases video quality over VoIP transmission.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.
