Publication number: 20180227769Abstract: The present application provides a method and system for sharing of unlicensed spectrum. The disclosed method and system when implement improves the spectral efficiency of LTE users and also improves the overall performance of LAA and Wi-Fi users. A BS senses the channel for any ongoing transmissions for a CCA period which is equal to DIFS time period of Wi-Fi. If the channel is busy (CCA-busy), it enters into back-off stage by selecting a uniform random number from [0, C0?1] as the back-off counter, where C0 is the fixed congestion window size. If the channel is free for a CCA period (CCA-idle), the back-off counter gets decremented by unity until it reaches zero. Once the back-off counter reaches zero, LAA again senses and schedules its down-link transmissions for a maximum channel occupancy period, provided the channel is free.Type: ApplicationFiled: February 8, 2018Publication date: August 9, 2018Applicant: Tata Consultancy Services LimitedInventors: Visali MUSHUNURI, Bighnaraj PANIGRAHI, Hemant Kumar RATH, Anantha SIMHA

Publication number: 20170207974Abstract: A method and system is provided for distributed optimal caching for information centric networking. The system and method disclosed herein enables each router/node in the network to make an independent decision to solve the optimization problem based upon a cost feedback from its neighbors. Content is received by a first router which determines if it should store the content in its cache based on a Characterizing Metrics (CM) value or send it to a neighbor router j, where the neighbor router j is selected based on a transaction cost determination. The node j on receiving the content shared with itself again performs similar computation to determine if the content should be stored in its cache. The method is performed iteratively for optimal distributed caching.Type: ApplicationFiled: November 21, 2016Publication date: July 20, 2017Applicant: Tata Consultancy Services LimitedInventors: Samar SHAILENDRA, Bighnaraj Panigrahi, Senthilmurugan Sengottuvelan, Hemant Kumar Rath, Anantha Simha

Publication number: 20160360000Abstract: A technique for estimating cache size for cache routers in information centric networks (ICNs) is disclosed. In an example, an average rate of incoming requests and a probability of occurrence of each request at a cache router in a predefined time interval is determined. Further, a relation between cache hit and cache miss with and without replacement is derived based on the probability of occurrence of each request. Furthermore, an entropy of the requests is computed based on the probability of occurrence of each request. Moreover, a diversity index of the requests is calculated based on the entropy and the average rate of the requests. A cache size for the cache router is then estimated based on a user defined probability of cache hit, the average rate of the requests, the diversity index of the requests and the relation between the cache hit and cache miss with and without replacement.Type: ApplicationFiled: March 9, 2016Publication date: December 8, 2016Applicant: TATA CONSULTANCY SERVICES LIMITEDInventors: Bighnaraj PANIGRAHI, Samar SHAILENDRA, Hemant Kumar RATH, Anantha SIMHA
