With the development of mobile communication technologies and the popularity of relating devices, GSM network-based intelligent systems have been used more and more widely. Most existing intelligent systems have built on mobile platforms, but those systems don't provide any facility that could save time and energy. But people suffer from lack of time and energy to buy essential needs like medicine, etc. and they like to communicate to the supplier to get confirmation instantly before leaving home or office to collect the same. So, in society, it needs to give alignment without going on field. This chapter copes this problem using wireless database searching scheme using GSM technology, which is very useful in smart cities, where cell phone is an essential part of living. The system receives information from outsiders and customers through GSM modem database searches of all the suppliers connected in a common server and sends the result through short messages independently to the customer showing the availability.
TopIntroduction
The wireless data services associated with communication industry becomes flourishing day by day (Pahlavan & Levesque, (1994); Zheng, Lee & Lee, (2007); Jamil, (2008); Cao, (2009); Wang, (2010); Figueiredo, Riberio, & Conforti, (2011). Many academicians as well as industry personnel have come forward to develop the wireless network area and also making it more and more popular. Point-to-point access employs a basic client-server model, where the server is responsible for processing a query and returning the result to the client via a dedicated point-to- point channel (Hu, Lee & Lee, (1999); Zheng, Lee & Lee, (2007)). Wireless data services and systems represent a rapidly growing and increasingly important segment of the communications industry. While the wireless data industry is becoming increasingly diverse and fragmented, one can identify a few mainstreams, which relate directly to users' requirement for data services (Pahlavan & Levesque, (1994); Jamil, (2008); Cao, (2009); Wang, (2010); Haifeng, (2010); Hu, Lee & Lee, (1999)). With the widespread deployment of wireless networks and the fast growing popularity of smart mobile devices, there has been an increasing interest in wireless data services from both industrial and academic communities in recent years. Point-to-point access employs a basic client-server model, where the server is responsible for processing a query and returning the result to the client via a dedicated point-to-point channel (Zheng, Lee & Lee, (2007); Figueiredo, Riberio, & Conforti, (2011)). For instance, in search of a medicine people must go to the medicine shop nearby and if it is unavailable they search to the other shop. But in an emergency situation, it is a bit difficult and also the condition of the patient deteriorate. Even, the customer can get the conformation via email or phone calls for the required medicine, but it is dependent on the staff and customer must wait for reply.
The advancement of mobile computing technologies in recent years has contributed to the growth of smart cities. Though internet may be indispensable today, but still it is not that friendly for many of the users. But nowadays, most of the users know to operate the mobile phones and write messages. For this simplicity, the Global System for Mobile communication (GSM) digital wireless network has been developed (Haifeng, (2010); Ansari, Navada, Agarwal, Patil & Sonkamble, (2011)). It may be used to transmit data at rates of 9600 bits/s. From anywhere people can get the valuable information about any medicine from the common server with the name and address of a store. SMS messages can be sent between users or to and from an application, which gives service development an extra flexibility that encourages innovation (Hansen, (2001); Ansari, Navada, Agarwal, Patil & Sonkamble, (2011)). Basically it interacts between medicine shop server and external world. It is low cost, user-friendly and convenient for secondary development.
In order to overcome this problem, a wireless medicine database searching scheme has been developed. People can get the valuable information from anywhere about any medicine and its availability from any shop.
In the present chapter, an attempt has been made to establish a communication between customer and medicine shopkeeper using wireless data services through SMS alert.
