[en] Nowadays technology is part of the daily life of modern society, offering multiple services to users, with endless purposes. Being intelligent telephony the most integrated technology at present, most of the services can be accessed by users using applications installed on these mobile devices, drawing a high mobility and connectivity environment. This scenario coupled with the need for individuals to communicate with their environment, make instant messaging applications the most popular among smart phone users. The wide variety of applications available in the market with this purpose, contrasts with the trend of the end users, presenting a monopolized situation in which the clients with private license are the ones that have a greater presence in the market. In this framework is presented the work in this document, which consists in the analysis of the alternatives available for instant messaging applications, based on the XMPP protocol (Extensible Messaging and Presence Protocol) with free license in Android devices. With this objective, to see the real situation of instant messaging, statistical data related to the habits of use of instant messaging in real users is analysed, as well as data about the state of the most relevant applications in the market. The reason for this statistical study lies in the need to know the parameters that make up the scenario in which the comparative of the various clients is performed, making possible to evaluate their suitability and future integration options in it. Taking into account the above, this document details the technical study performed, and the parameters and procedures used to obtain and analyse them. The obtained data could be used by developers and users, in a way that they facilitate the decision making around the choice of which client adapts better to their interests, on the basis of an empirical and objective analysis.

[eu] Gaur egun teknologia gizarte modernoaren eguneroko bizitzaren funtsesko partea da, makina bat serbitzu ezberdin eskainiz erabiltzaileei, helburu anitzekin. Telefonia adimentsua egun integrazio handiena izan duen teknologia da, bere serbitzu gehienak telefono mugikorretan instalatutako aplikazioen bidez erabitzen direla, mugikortasun eta konektibitate handiko egoera faboratuz. Agertoki honek, norbanakoen komunikatzeko beharrarekin batera, bat-bateko mezularitza aplikazioen populartasuna bideratu dute telefonia adimentsuaren erabiltzaileen artean. Aplikazioen merkatuak duen aniztasuna, ez du bat egiten erabiltzaileen joera orokorrarekin ordea, egoera monopolizatu bat aurkeztuz, non lizentzia pribatudun aplikazioak erabiltzaileen gogokoenak agertzen diren. Izaera honetan kokatzen da dokumentu honetan aurkeztutako lana, XMPP (Extensible Messaging and Presence Protocol) protokoloa erabiltzen duten Android bat-bateko mezularitza aplikazio eskuragaien analisian oinarritzen dena, aplikazio guzti hauek lizentzia librea dutela. Horretarako, bat-bateko mezularitzaren egiazko egoeraren aztertzen da, benetazko erabiltzaileen erabilpen ohiturei eta merkatuari buruzko datu estadistikoak eskainiz. Azterketa honek gaur egungo egoera baldintzatzen duten parametroak ezagutzen lagunduko du, aplikazio ezberdinen egokitzapen eta etorkizunerako integrazio aukeren ebaluazioa egiteko aukera emanez. Aurrekoa gogoan izanik, dokumentu honetan, gauzatutako ikerketa teknikoa, erabilitako parametro eta prozedurak eta beren analisia aurkezten dira. Gararatzaile eta erabiltzaileek, eskuratutako datuak erabili ahal dituzte, beren beharrei zein aplikazio moldatzen den hobe erabaki-hartze prozesua errazteko, analisi enpiriko eta objektiboan oinarritutako datuak erabiliz.
