Today’s Push-to-talk (PTT) services are infrastructure based and require stable end-to-end paths for successful communication. However, users with PTT enabled mobile devices may roam in challenged environments where infrastructure is not available. In such cases the traditional PTT services may exhibit poor performance or even fail completely.(More)
Walkie-talkie kind of communication has been gaining attention as a service in cellular networks. Traditional walkie-talkie like services require network infrastructure for its operation. While infrastructure-less operation in mobile ad-hoc networks has been explored in the past, such approaches attempt to establish an end-to-end path for communications,(More)
Mobile ad-hoc networks, especially when they are sparse, are not well suited for ad-hoc voice communication when using end-to-end real-time audio streams: as paths grow in length, stability and forwarding performance suffer, and sometimes paths may not exist at all. In this paper, we suggest using asynchronous voice messaging built upon delay-tolerant(More)
Medical wastes are highly infectious and hazardous. It may carry the germs of dreadful diseases like hepatitis B and C (jaundice), and HIV/AIDS. It contains toxic chemicals and hazardous materials from several diagnostic and treatment processes. The improper disposal of Medical waste in the CMCH poses a high health risk to humans as well as the environment.(More)
