Investigation of Quick Handover Algorithm for Wireless Video Streaming App


Published on

Developed and tested an effective handover algorithm for uninterrupted live mobile video streaming with high quality of service and performance efficiency based on 802.11g standards using an ARM 9 processor, designed a successful system architecture using JavaScript and C languages, JAX-WS Web services, MYSQL database and NetBeans integrated development environment, simulation results were observed in terms of the number of handovers versus RSS (Reduced Signal Strength.) - Presented by Rajvi Desai, Sayali Dharmadhikari, Sunayana Goswamy

  • To aid the research on Video Streaming Applications which will improve Quality of Service in the form of noise, jitter, delay, heterogeneity, adaptation, bandwidth utilization, and migration
  • The handover decision is made upon received signal strength by base station from the mobile station Negotiation between MS, BS 1 & BS 2 Decision Making Priority strategies during overloading
  • As part of strategic planning we carry out SWOT Analysis S trengths: attributes of the person that are helpful to achieving the objective. W eaknesses: attributes of the person that are harmful to achieving the objective. O pportunities: external conditions that are helpful to achieving the objective. T hreats: external conditions which could do damage to the business's performance.
  • An exit strategy is a means of escaping one's current situation, typically an unfavourable situation. An organization or individual without an exit strategy may be in a quagmire .
