Each issue of the IEEE Journal on Selected Areas in Communications (JSAC) is devoted to a specific technical topic and thus provides to JSAC readers a collection of up-to-date papers on that topic. These issues are valuable to the research community and become valuable references. The technical topics covered by JSAC issues span the entire field of communications and networking. JSAC publishes only papers that are submitted in response to a Call-for-Papers. These calls are published in JSAC issues and other publications of the IEEE Communications Society as appropriate to the subject area of the call. Papers submitted for review for possible publication in a JSAC issue must be submitted to one of the Guest Editors listed in the Call-for-Papers. See "Information for Authors" found in any JSAC issue for additional instructions. Topics for JSAC issues are determined by the JSAC Editorial Board after review of proposals submitted by interested parties. All are invited to submit proposals. Instructions for submitting proposals are included in the Guidelines for Proposal preparation on the JSAC website. Recent issue themes included: Network Coding for Wireless Communication Networks, Wireless and Pervasive Communications for Healthcare, Network Infrastructure Configuration, Broadband Access Networks: Architectures and Protocols, Body Area Networking: Technology and Applications, Underwater Wireless Communication Networks, Game Theory in Communication Systems, Exploiting Limited Feedback in Tomorrow’s Communication Networks.
