  How Long to Wait? Predicting Bus Arrival TimeWith Mobile Phone Based Participatory Sensing The bus arrival time is primary information to most city transport travelers. Excessively long waiting time at bus stops oftendiscourages the travelers and makes them reluctant to take buses. In this paper, we present a bus arrival time prediction systembased on bus passengers’ participatory sensing. With commodity mobile phones, the bus passengers’ surrounding environmentalcontext is effectively collected and utilized to estimate the bus traveling routes and predict bus arrival time at various bus stops. Theproposed system solely relies on the collaborative effort of the participating users and is independent from the bus operatingcompanies, so it can be easily adopted to support universal bus service systems without requesting support from particular busoperating companies. Instead of referring to GPS-enabled location information, we resort to more generally available and energyefficien

AN ANDROID APP FOR THE SAFETY OF WOMEN In today’s world, people using smart phones have increased rapidly and hence, a smart phone can be used efficiently for personal security or various other protection purposes. The heinous incident that outraged the entire nation have waken us to go for the safety issues and so a host of new apps have been developed to provide security systems to women via their phones.

The unique feature of this application is to send the message to the registered contacts continuously for every five minutes until the “stop” button in the application is clicked. Continuous

A SMART WATCH FOR WOMEN SECURITY BASED ON IOT CONCEPT‘WATCH ME’ Abstract:   Today, in the current global scenario, Women were facing lot of challenges. We can hear the news of women harassments than their achievements. There are many existing apps and devices for women security via smart phones. Though the smart phones have increased rapidly, it is not possible to have the phone all the time in our hand to make a call or click on it, so here we introduced a new technique via smart watches. When a women or child wearing this ‘watch me’ is exposed to sexual or vulnerable attack, the sensor present in it detects the heart beat rate of a person which will be high at the moment by the secretion of epinephrine hormone from hpa axis and gets activated, this will not only provide a alarm sound to the attention of nearby people, it will automatically make an call to our registered contact and also through GPS/GSM it will detect the nearby police station and make an ring there s
